Enable XOOPS CAPTCHA with extensible methods.
Currently available methods: text and image.
Image method requires GD library, based on dugris' securityImage package.
Image method can be extended to bmp, on TODO list
I think that you should also enable use of imagemagik graphics library. In my experience some hosters will allow one or other of these, but often not both. there seem to be conflicting arguments about the security of both of these libraries. That's my 2 cents worth :-)
Ashley, thanks for reminding me of imageMagik.
Do you have any tips or code sample for imageMagik based CAPTCHA?
I haven't dealt with imageMagik for years.
