Store images on steroids

Hey there..I set up the Market store that came with the plugins, so far I really like it! The one issue I am having, is the product image sizes. I upload an image that is 275 X 320 for example and the store increases it to 522 X 531. I have gone through all of WP setting and set the default image sizes to 200 X 200 (medium), I have made sure the images are the correct size in the media library and still my images grow when placed in the store.
Please help take my images off steroids before its to late :slight_smile:
Thanks in advance for the help.
