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:

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?

It turns out I didn't push the code changes to the live server yet. So regenerating thumbnails did nothing. Whoops. Its working now. :) – brant Jul 21 '11 at 18:00

Try installing Ajax Rebuild Thumbnails

This will create the new image size.
