This is How to Use the Original Image Size in WordPress
As a WordPress developer or site owner, you've likely encountered the challenge of displaying images at their original size on your website. While WordPress provides a range of image size options, such as "thumbnail," "medium," and "large," sometimes you may want to display the full-resolution image without any cropping or resizing.
In this article, we'll dive into the solution to this common WordPress issue and show you how to use the original image size in your WordPress website.
Understand the Default Image Size Settings in WordPress
By default, WordPress automatically generates several image sizes when you upload an image to your media library. These sizes are known as "image thumbnails" and are created to provide different size options for your content. The available image sizes in WordPress are:
- Thumbnail: A smaller version of the image, typically 150×150 pixels.
- Medium: A medium-sized version of the image, usually around 300×300 pixels.
- Large: A large version of the image, typically around 1024×1024 pixels.
- Full Size: The original, unmodified image size.
When you insert an image into your WordPress content, the default behavior is to use one of the generated thumbnail sizes, such as "medium" or "large," rather than the full-size image.
This approach has several benefits, including:
- Faster Page Load Times: Smaller image sizes require less bandwidth and load faster, improving the overall user experience.
- Responsive Design: The different image sizes allow WordPress to serve the appropriate size based on the user's device and screen resolution, ensuring a better responsive layout.
- Efficient Storage: Storing multiple versions of the same image saves disk space compared to keeping only the original high-resolution version.
However, there may be instances where you want to display the original, full-size image on your website. This could be the case for high-resolution hero images, product photos, or any other content where the full-quality image is essential.
Use the "full" Parameter to Display the Original Image Size
To display the original image size in WordPress, you can use the the_post_thumbnail()
function with the 'full'
parameter. Here's how you can do it:
the_post_thumbnail( 'full' );
Alternatively, you can use the get_the_post_thumbnail()
function:
echo get_the_post_thumbnail($post, 'full');
Both of these methods will output the original, full-size image for the current post or page.
Here's a step-by-step guide on how to implement this in your WordPress theme:
-
Locate the template file: Identify the template file where you want to display the original image size. This is typically in the content.php
, single.php
, or page.php
file, depending on your theme structure.
-
Replace the image size parameter: Find the existing the_post_thumbnail()
or get_the_post_thumbnail()
function call and replace the image size parameter with 'full'
.
For example, if your existing code looks like this:
the_post_thumbnail( 'medium' );
Replace it with:
the_post_thumbnail( 'full' );
Or, if you're using get_the_post_thumbnail()
:
echo get_the_post_thumbnail($post, 'medium');
Replace it with:
echo get_the_post_thumbnail($post, 'full');
- Save the changes: Save the template file, and your WordPress website will now display the original image size on the selected pages or posts.
Considerations and Best Practices
While using the original image size can be beneficial in certain scenarios, there are a few things to keep in mind:
-
Performance Impact: Displaying large, high-resolution images can significantly impact your website's performance and loading times. Ensure that you optimize your images for the web by compressing them and using appropriate file formats (e.g., JPEG, WebP) to minimize file size without sacrificing quality.
-
Responsive Design: When using the original image size, your website may not adapt well to different screen sizes and devices. To maintain a responsive design, consider using the WordPress srcset
and sizes
attributes to provide multiple image sizes and allow the browser to choose the most appropriate one based on the user's device.
Here's an example of how to use srcset
and sizes
with the original image size:
the_post_thumbnail( 'full', array(
'srcset' => array(
get_the_post_thumbnail_url( $post, 'full' ) . ' 1200w',
get_the_post_thumbnail_url( $post, 'large' ) . ' 1024w',
get_the_post_thumbnail_url( $post, 'medium' ) . ' 768w',
get_the_post_thumbnail_url( $post, 'thumbnail' ) . ' 150w',
),
'sizes' => '(max-width: 1200px) 100vw, 1200px',
) );
This code will provide the browser with multiple image size options, allowing it to choose the most appropriate one based on the user's screen size, while still using the original image size as the primary source.
-
Accessibility: When displaying high-resolution images, make sure to provide appropriate alt
text to ensure accessibility for users who may have difficulty viewing the images.
-
Compatibility: Ensure that the "full" image size is available and appropriate for your use case. Some WordPress plugins or custom image size functions may override or modify the "full" size, so you may need to adjust your code accordingly.
By following these best practices, you can effectively use the original image size in your WordPress website without compromising performance, responsiveness, or accessibility.
Conclusion
Displaying the original image size in WordPress is a straightforward process using the the_post_thumbnail()
or get_the_post_thumbnail()
functions with the 'full'
parameter. This approach can be useful in scenarios where the full-quality image is essential, such as hero images, product photos, or high-resolution content.
However, it's important to balance the use of original image sizes with performance considerations, responsive design, and accessibility. By implementing the techniques discussed in this article and following best practices, you can ensure that your WordPress website provides an optimal user experience while showcasing your content in its full glory.
