Rounded corners on thumbnail/post images?
Is it possible to automatically generate rounded corners on all images that are set as Featured Image in a post? Meaning the small 100x100 thumbnails in the Featured Ads section as well as the larger thumbnails in the recent posts section.
I'm assuming there's a CSS trick to this, but it's not clear to me how I'm going to accomplish this in conjunction with the PHP call that's generating the images.
Thanks in advance for any help.
