Ok this is driving me a bit mental and it's possible I've been looking at it too long to see the answer anymore, and it seems so simple.
When a product is listed if the product image isn't the same dimensions as the display box it places a white surround to it. Ok sounds simple enough to sort just change the CSS.
Hmmm i have been all through the CSS and added my own but the images still get a white background.
When i use the same images in image_gallery they are displayed fine no surround unless i specify it so my question is where the hell is the eccomerce module getting the idea of putting a white surround on the images i can't see it in any of the CSS.
if your unsure what i mean heres the site http://gallery90.myriad-services.co.uk/online-store/
hope you can help put me out of my misery.
