Image size should not be a problem. The images are just graphic designs and none are over 100KB. I suppose the server speed could be a problem, I am using network solutions as a host and have never even come close to having a problem with them. That being said, it appears I have found a temporary fix to the problem. If I load up all the product images that I want for a certain product, only a few load correctly. If I then switch my file permissions on my entire shopping cart around a few times between the 775 they were originally at, 755, and 777, then all the thumbnail appear and the images seem to be working perfectly. If anyone has a better solution to the problem I would still love to hear it because this method is pretty inefficient for a large number of products and photos. Thanks.
