Hey Limpia - I *believe* there is an option to "turn off" the store window - go to the 'store' tab at the top, click on the box that says 'store window' (Believe it is upper left hand corner?) and click the checkmark boxes to make everything hidden. That might take care of it.
Also, Auctiva apparently switched image servers recently and some have been having a bit of a tough time with photos, both store window and otherwise. This may be a temporary thing, so don't discount store window entirely
Best of luck to you!
