My default thumbnail size is 150x150. Therefore, if I use a custom thumbnail size, such as 75x75 it should use the thumbnail of 150x150 and shrink to fit to my size:
get_the_post_thumbnail( $item->ID, array(75,75))
However, it is basing the image off of a thumbnail size of 149x100. The 150x150 image exists, but it refuses to use it.
I figured heck with that, I'll just create a custom 75x75 thumbnail and that will solve the problem:
functions.php add_image_size( 'listp-thumb', 75, 75, true ); // thumbnails located in list posts
Now to call the new thumbnail:
get_the_post_thumbnail( $item->ID, 'listp-thumb')
The same thing happens. :( Do I need to clear a custom query that may be interfering with this?
