Hello,

It is possible, but would require a bit of custom work. Please try:

1. Create a new child theme by following this guide: https://uxbarn.ticksy.com/article/8649/

2. In the "functions.php" file of the child theme, add this code:

function viceversa_register_theme_image_sizes() {
        
        add_image_size( 'viceversa-blog', 640, 9999 );
        add_image_size( 'viceversa-port-list', 9999, 500 );
        add_image_size( 'viceversa-port-single-landscape', 760, 9999 );
        add_image_size( 'viceversa-port-single-portrait', 480, 9999 );
        
    }

Notice the "'viceversa-port-list'" entry that the last number is now 500 which means 500px height (the original one is 220.)

The "add_image_size()" is the WordPress function for creating custom image sizes to be used. For more info, please see: https://developer.wordpress.org/reference/functions/add_image_size/

3. So, we just override the parent theme's image sizes in our child theme. In this step, install and activate the Regenerate Thumbnails plugin: https://wordpress.org/plugins/regenerate-thumbnails/

4. Go to "Tools > Regenerate Thumbnails" and after it's done, if you check the portfolio images on the front-end, the 220px height image should now be 500px height as we set.

I hope this helps!

Regards,
Paul
