Thanks. I'm looking specifically for something that will generate an image though, as I need to include it in BBCode scripting.
Most web-programming languages have a function that can generate an image or a captcha or something from a string of text.... not so sure about BBCode.
If you own any other websites, it might be a good idea to generate/host the image there and just embed it on your Minecraft Forum.
Thinking... thinking...
.... if you could pick out what you want specifically from an exchange's API info, you could have it submitted to a graphical service, or some such text-to-image generator for free:

Good luck botting!
