Hi Tom, Unfortunately, I wanted to stay away from javascript because some people turn it off in their web-browsers for security reasons.
The solution I finally used was to just rename the image so that it looked new to the web-browser, and then update the database with the new name. I did it using LiveCode so no javascript was required. Thanks for your suggestion anyway.
