To follow up, if I were to go about this in a brute force manner, by simply saving the dynamically generated figure to a randomly generated file and then passing that file to an AREA MAP / IMG tag, where in the web2py directory structure would be the recommended place to do so? I suppose using the SQLLITE database might be a natural option. Any opinions? Are there any examples of doing something like this? I suppose it's vaguely similar to a photo album application, except the photos are dynamically created and deleted after use. Thanks, G
