Rob, when replying to this post, use the "switch to full reply" button which allows you to upload images. At the very top of the response form, above the "Screen Size" information, there is a link to optimize your image. There is a 300K size limit for images. Once your image is optimized, it will upload successfully,
One trick to reduce image size is to crop the image closely around the stamp to remove unneeded waste that increases the file size.
