Disable Large Image Scaling in WordPress 5.3 Easily
Explanation
WordPress 5.3 introduced a feature that automatically scales down large images to help with performance and storage. However, if you want to keep your images at their original size, you can disable this feature.
The code snippet provided does just that. It uses a filter called big_image_size_threshold to change the scaling behavior. By setting the threshold to 0, it effectively turns off the automatic scaling feature.
Here's a quick breakdown of what happens:
- The function
wp_dudecom_disable_large_image_scalingis created to modify the scaling threshold. - It returns
0, which tells WordPress not to scale any images. - The
add_filterfunction connects this custom function to thebig_image_size_thresholdfilter, applying the change.
By adding this snippet to your theme's functions.php file, you can stop WordPress from automatically resizing your images.
Code
<?php
/**
* Disable large image scaling in WordPress 5.3 and above.
*
* WordPress 5.3 introduced a feature that automatically scales down large images.
* This snippet disables that feature.
*
* @param int $threshold The threshold value for scaling images.
* @return int The modified threshold value.
*/
function wp_dudecom_disable_large_image_scaling( $threshold ) {
return 0; // Return 0 to disable scaling.
}
add_filter( 'big_image_size_threshold', 'wp_dudecom_disable_large_image_scaling' );
