set_post_thumbnail_size( 80, 80, true ); // true for all post types
Suppose I have two post types in play on my blog: Post, Video and Product. I may want a 80x80 image size for my posts, but 100x100 for my videos and a 50x100 for my Products. To my knowledge, I am forced to create thumbnails for my Post images in the dimensions of 100x100 and also 50x100. And for my products, I'm forced to create thumbnails that are 80x80 and 100x100, even though I won't use those ever.
Is there a way to create image sizes that are based on post types so you don't end up making a bunch of images you don't plan on using, and wasting resources that could be used elsewhere?
