Fuzzy Images inTwenty Twelve Canvas theme

Hi there..

I installed the woo commerce plugin having thoroughly tested it using a temporary shop account. It looked great. So, I deleted my lovely ecommerce theme (which was time consuming to customise, that’s why).

I am using the woo plugin with Twenty Twelve, the images look awful despite following the advice in a tutorial written by a WOO person which involved right clicking to find out the altered dimensions of images and changing the width and height in the plug in settings to match. So, I am now faced with having to purchase a new theme to get it to look right. So, my question is, if I buy the Canvas theme, can I be reassured that the images will be of good quality. My shop is to sell original illustrations, prints, postcards etc.

Looking for an answer from WOO please?
