AJAX IMAGE SWAPPER SORT ORDER

I seem to have lost control of the order in which my images are displayed...For example [login to view URL];cPath=1_2&products_id=45 I want the hard saddlebag picture to be first to display....I can't seem to fix it in AJAX image swapper..even if I change the sort order... I was hoping to find some file somewhere that I could edit to display the order I want... Also, sometimes I have the wrong image for a product...I can't edit it to change the picture...so I delete it ...right?! But then it deletes from the 'images' folder... Geez ..I'm going nuts...
