zoom gallery forcing images to be 200px x 200px

Hi there is a bit of code somewhere in the plugin that is forcing my gallery images to be 200px x 200px when they are specified (and actually are) 150px wide x 200px high. can you help me sort this out? I would really like to use your plug in but right now I can’t. I’m using the latest version of woocommerce and the latest version of woo canvas.
