If you’re managing a WordPress website, you know how important it is to keep your content organised. One way to make your life easier is by adding thumbnail images to your admin posts list. These small pictures can help you spot the right post quickly without reading through every title. They can also help you locate posts that are missing a featured image. Both can be game-changing if you have a lot of posts.
This guide will show you how to add featured image thumbnails to your WordPress admin area. Whether you’re new to WordPress or an experienced user, we’ve got you covered. We’ll explain everything step by step, so don’t worry if you’re not a tech expert!
Before we dive in, let’s clarify a few terms:
- WordPress admin: This is the behind-the-scenes area where you manage your website.
- Featured image: The main picture represents a post or page on your site.
- Thumbnail: A miniature version of a larger image.
By the end of this guide, you’ll be able to see small preview images next to your posts in the admin area, making it much easier to manage your content.
Add Thumbnail to WordPress Posts List – Guide
When you log into your WordPress admin area and go to the ‘Posts’ section, you’ll see a list of all your blog posts. This list, called the WordPress Admin Posts List, usually shows several columns of information for each post. Let’s break down what you typically see:
- Title: The name of your post.
- Author: Who wrote the post.
- Categories: The groups your post belongs to.
- Tags: Keywords associated with your post.
- Comments: How many comments the post has received.
- Date: When the post was published or last modified.
These columns help you organise and find your posts quickly. However, there’s one thing missing: a visual preview of each post.
Why Add a Featured Image Thumbnail to the Posts List?
Adding a featured image column to this list can be incredibly helpful. Here’s why:
- Quick identification: Pictures are more accessible than text, especially when scrolling through a long list.
- Content verification: You can quickly check if the right image is attached to each post.
- Visual appeal: It makes your admin area more attractive and user-friendly.
- Time-saving: You won’t need to open each post to check its featured image.
In the next section, we’ll show you how to add this valuable feature to your WordPress admin. It’s simpler than you might think!
Step-by-Step Guide to Adding Featured Image Thumbnails
Now, let’s get to the exciting part – adding those handy thumbnail images to your posts list. Don’t worry if you’re not a coding expert; we’ll guide you through each step.
A. Accessing your theme’s functions.php file
First, you need to find your theme’s functions.php file. This is a special file that controls many of your website’s features. Here’s how to find it:
- Log in to your WordPress admin area.
- Go to ‘Appearance’ > ‘Theme Editor’ in the left sidebar.
- Look for ‘Theme Functions (functions.php)’ in the list on the right side.
If you can’t find this option, you might need to use an FTP client or ask your web host for help.
B. Adding the necessary code
Now, we’ll add the code that creates the thumbnail column. Don’t panic – you don’t need to understand every line. Just copy and paste this code at the end of your functions.php file:
// AIO Spark Featured Image Thumbnail - Start
function add_featured_image_to_admin_posts_list($columns) {
$new_columns = array();
foreach ($columns as $key => $value) {
if ($key == 'title') {
$new_columns['featured_image'] = 'Featured Image';
}
$new_columns[$key] = $value;
}
return $new_columns;
}
add_filter('manage_posts_columns', 'add_featured_image_to_admin_posts_list');
function display_featured_image_in_admin_posts_list($column_name, $post_id) {
if ($column_name == 'featured_image') {
$featured_image = get_the_post_thumbnail($post_id, array(50, 50));
echo $featured_image ? $featured_image : 'No Image';
}
}
add_action('manage_posts_custom_column', 'display_featured_image_in_admin_posts_list', 10, 2);
// AIO Spark Featured Image Thumbnail - End
After pasting the code, click ‘Update File’ to save your changes.
C. Explaining the code (for beginners)
If you’re curious about what this code does, here’s a simple explanation:
- The first function creates a new column called ‘Featured Image’ in your posts list.
- The second function tells WordPress what to show in this new column – either a small version of your featured image or the text ‘No Image’ if there isn’t one.
That’s it! You’ve just added a new feature to your WordPress site.
Testing and Troubleshooting
Now that you’ve added the code, it’s time to check if it’s working properly. Let’s go through the testing process and look at some common issues you might face.
A. Verifying if the code is working
- Go back to your WordPress admin area.
- Click on ‘Posts’ in the left sidebar.
- Look for a new column called ‘Featured Image’ in your posts list.
- You should see small thumbnails (or ‘No Image’ text) in this column.
If you can see the new column with thumbnails, congratulations! The code is working as intended.
B. Common issues and their solutions
If you don’t see the new column, or if something doesn’t look right, don’t worry. Here are some common problems and how to fix them:
- No ‘Featured Image’ column:
- Double-check that you pasted the entire code snippet.
- Make sure you clicked ‘Update File’ after adding the code.
- Try clearing your browser cache and refreshing the page.
- Column appears but no images show:
- Ensure your posts have featured images set.
- Check if your theme supports featured images.
- Images are too big or too small:
- You can adjust the image size in the code. Look for ‘array(50, 50)’ and change these numbers to your preferred size.
- The website looks broken:
- If your site looks odd after adding the code, you might have accidentally deleted part of the existing code in functions.php. Try undoing your changes or restoring a backup.
C. Compatibility considerations
Keep in mind that this code should work with most WordPress themes and plugins. However, if you’re using a complex theme or have many plugins, there might be conflicts. If you experience any strange behaviour on your site after adding this code, try deactivating plugins one by one to identify the cause.
Remember, if you’re not comfortable making these changes yourself, it’s always best to ask for help from a WordPress developer or your website host.
Enhancing the Feature (for Advanced Users and Brave N00bs)
If you’re comfortable with coding and want to take this feature further, here are some ways to customise and improve it:
A. Modifying thumbnail size
You can easily change the size of the thumbnails in your admin list. In the code we added earlier, find this line:
$featured_image = get_the_post_thumbnail($post_id, array(50, 50));
The ‘array(50, 50)’ part sets the width and height of the thumbnail in pixels. Change these numbers to adjust the size. For example, ‘array(80, 80)’ would make larger thumbnails.
B. Adding custom CSS for better presentation
To make your thumbnails look even nicer, you can add some CSS. Here’s how:
- Go to ‘Appearance’ > ‘Theme Editor’ in your WordPress admin.
- Look for your theme’s style.css file in the right sidebar.
- Add this CSS code at the end of the file:
.column-featured_image img {
border-radius: 5px;
box-shadow: 0 1px 3px rgba(0,0,0,0.1);
}
This will give your thumbnails rounded corners and a subtle shadow. Feel free to adjust these styles to match your preferences.
C. Extending the functionality to custom post types
If your website uses custom post types (special types of content), you can show thumbnails for these too. Add this code to your functions.php file, replacing ‘your_custom_post_type’ with the name of your custom post type:
add_filter('manage_your_custom_post_type_posts_columns', 'add_featured_image_to_admin_posts_list');
add_action('manage_your_custom_post_type_posts_custom_column', 'display_featured_image_in_admin_posts_list', 10, 2);
This will apply the same thumbnail feature to your custom post type.
Remember, these advanced tweaks are optional. If you’re not confident about making these changes, the basic setup we did earlier works great on its own.
Best Practices for Using Featured Images in WordPress
Now that you’ve set up featured image thumbnails in your admin area, let’s talk about how to make the most of this feature. Here are some tips for choosing and using featured images effectively:
A. Choosing appropriate images for posts
- Relevance: Pick images that relate closely to your post content. This helps readers quickly understand what the post is about.
- Quality: Use clear, high-resolution images. Blurry or pixelated pictures can make your site look unprofessional.
- Consistency: Try to maintain a similar style across your images. This could mean using the same colour scheme or type of imagery.
- Originality: When possible, use unique images or photos you’ve taken yourself. This sets your content apart from others.
B. Optimising images for web performance
- File size: Large image files can slow down your website. Aim to keep your images under 100KB if possible.
- Image dimensions: Resize your images to fit your theme before uploading. There’s no need for a 4000px wide image if your content area is only 800px wide.
- File format: Use JPEGs for photographs and PNGs for images with text or simple graphics.
- Compression: Use tools like TinyPNG or ImageOptim to reduce file sizes without losing quality.
C. Maintaining consistency in image styles
- Aspect ratio: Try to use the same shape for all your featured images. If your theme displays square thumbnails, make sure all your images look good in a square format.
- Branding: Consider adding your logo or website name to featured images. This can help if your images are shared on social media.
- Text overlays: If you add text to your images, use the same font and text placement across all posts.
- Colour scheme: Using a consistent colour palette in your images can make your site look more cohesive.
By following these best practices, you’ll not only make your admin area more organised but also improve the overall look and performance of your WordPress site.
SEO Benefits of Proper Featured Image Usage
When it comes to search engine optimisation (SEO), every element of your website plays a role – including your images. Proper use of featured images can significantly boost your site’s visibility and ranking in search results.
How these visuals can enhance your SEO efforts.
Firstly, attractive featured images can dramatically increase user engagement. When potential visitors see an eye-catching image alongside your content in search results or social media shares, they’re more likely to click through to your site. This increased click-through rate signals to search engines that your content is relevant and valuable, potentially improving your rankings.
Moreover, compelling visuals encourage visitors to spend more time on your page. This extended ‘dwell time’ is another positive signal to search engines, suggesting that users find your content worthwhile. A well-chosen featured image sets the tone for your article and can entice readers to explore further.
Don’t forget about Google Image search
An often-overlooked source of traffic. Your featured images, when optimised correctly, can appear in image search results, drawing in users who might not have found your site through traditional text-based searches.
Technical aspects of image optimisation
Alt text is crucial – it describes your image for those who can’t see it, whether due to visual impairments or slow internet connections. Search engines also use alt text to understand the content of images. When writing alt text, aim for clear, concise descriptions that include your target keyword if it fits naturally. For instance, instead of “beach1.jpg”, you might use “Woman practising yoga on a sunset beach”.
File names are equally important. Before uploading any image, rename it with a descriptive title using lowercase letters and hyphens instead of spaces. This helps search engines understand the image content before they even analyse it. Following our previous example, a good file name might be “woman-yoga-sunset-beach.jpg”.
While not always necessary, image captions can provide additional context and another opportunity to naturally include keywords. They’re also frequently read by users skimming content, making them valuable for both SEO and user experience.
Lastly, remember that image size and format affect page load speed, which is a significant ranking factor. Optimise your images for quick loading without sacrificing quality. And whenever possible, use unique, original images rather than stock photos – this can help your content stand out in image search results.
Final Word on SEO Benefits of Featured Images
By paying attention to these details, you’re not just making your WordPress admin more organised – you’re setting your entire site up for SEO success. Remember, though, that while optimising for search engines is important, your primary focus should always be on creating high-quality, relevant content for your human readers. Striking this balance is the key to long-term success in the digital landscape.
