With some themes, on the landing page, and almost always in archives with any theme, two thumnail images display side by side. They are in a class entry-content div, with 2 a herf= tags one after another.
This is exclusively with images that are generated by other featured image plugins, so I do not believe that this plugin is responsible for this occurring, but thought I would toss the question of how to remove one of the images out to the knowledgeable people here.
