My category archives page displays thumbnail images for each post. The problem is that under the majority of the thumbnail images (but not all), there is a PARTIAL duplicate thumbnail image. It's just a thin strip of the thumbnail, really. But it's enough to look awful. Here's an example: http://www.somethingswanky.com/category/breakfast/
Help, please? And I'm afraid I need VERY simplified instructions, using baby words. Most stuff in this forum goes straight over my head!
Oh, and also-- I have searched this. I've found some information on duplicate PHOTOS showing up, but I haven't found anything that's helped me with this specific issue.
