post thumbnail isn't using resized images
|Reported by:||Denis-de-Bernardy||Owned by:||MarkJaquith|
it seems like the new post thumbnail feature neither crops images, nor uses thumbnail images when available.
get_the_post_thumbnail() and set_post_thumbnail_size() seem to use the size of post-thumbnail, but image_downsize() only seems to understand a size of thumbnail.
this results in huge images in posts, even when the size is small.
