Hi XmanLewis,
If you have the "Image Borders" setting enabled in your Auctiva account, any images you place in the "Select an Image" boxes on the Auctiva lister page will automatically have image borders that ocrrespond with the template color scheme applied to them, so it is possible the image border settign has something to do with the problem you are facing.
If you would like further assistance with this matter, please file a support request using the appropriate link on our help page,
