I just uploaded an item "Casual set for Miki4" to the free stuff here. I included two images, one is 300 x 350 px and the other one is 993 x 887 pixels. My problem is that the small picture is used both in the "What's new" list and on the page for the product. Why is that? I see that most products have a large image on the details page.

The same thing happened with my "Ben Fauntleroy" item uploaded about three weeks ago.
