How big should the photos be to get high quality prints from them?
You should upload the best-quality images you have. On the server, we downsize all photos you upload to make them display faster on the web page, but we also keep the high-resolution original files on-hand for printing. We do have an upper limit on uploaded file size, which is 10MB – your file needs to be smaller than that to upload. 10MB would be a whopping huge picture though, so a good range to work with is between 2 to 4MB.
