I have a question on my "enlarge image" not showing up. Currently I have image width set to 100 and height to 0 so that ZC will automatically re-size them. I have read the tutorial posted with image instructions and optimizing my images. My problem is that I don't have access to the original photos being used since they are supplied by the host site. All products offered are from a parent company, and images are not my own. Any advice on how I can optimize the image size for my site?
