How is it possible to use original sized small images? I have a set of portrait and a set of landscape pics and I can either change the 'Image - Product Listing Width' to 0 (in admin - configuration - images) to make all the picture heights the original size or I can change the 'Image - Product Listing Height' to 0 and make the widths the original size but making them both 0 removes the image. I just don't know how to make them BOTH the original dimensions.

Help is appreciated as always.

_thanks
