The Vendio Gallery will work with any auction service you use -- you just have to make sure that you set up your image placement in such a way that the gallery does not grab logos, if you are using your own image hosting as the location of the images. I took a look at your settings for the Gallery as well as your items. I noticed that you have members.sparedollar.com as the image URL which is correct. Your first image setting is to use the 2nd image in the listing. Some of your items have the 2nd image as a logo and since they're all hosted at the same URL, that logo is being imported.
I would suggest perhaps changing it to the 3rd listing image since your items seem to have a lot of images (mostly logos for images 1 and 2). We can re-import your images if you make this change.
