Maybe we can help each other on this one? I’ve been working on something similar with no luck.
I got so far as creating a custom image size by adding something like this to the functions.php file:
if ( function_exists( 'add_image_size' ) ) {
add_image_size( 'homepage-thumb', 97, 83, true ); /* 97px wide by 83px tall */
}
add_filter( 'image_size_names_choose', 'my_custom_sizes' );
function my_custom_sizes( $sizes ) {
return array_merge( $sizes, array(
'homepage-thumb' => __('Homepage Thumbnail'),
) );
}
Replacing homepage-thumb with the name of your custom thumbnail size. Where it says “true” that just uses a soft proportional crop, instead of a hard crop. If you changed that to “false” it will create a new separate image file when you upload, rather than just resizing the original image to those proportions.
The problem I’m having, is the code to use that image isn’t working. I can’t even get it to show the default thumbnail size. I tried using your code above, like this:
<img src="<?php $homethumb = the_field('button_one_image'); echo $homethumb['sizes']['homepage-thumb']; ?>" />
I don’t know what I’m doing wrong though, I must be missing something.
