I am trying to get "captchas" to working on my Mediawiki installation, to use in conjunction with a guestbook. The author of the Mediawiki extension, which is written in php, says that the reason that the 'capchas' do not work is a problem with "certain distros" installation of php and certain features of GD. He does not elaborate. I have a out of the box installation of mediawiki, php5, and everything I can find that has 'gd' as part of it, all installed from Debian testing and up to date. The entire system seems to be working fine with no tweaking, except this particular feature. Anyone here who knows php & gd or anyone with any experience with getting this to work. BTW: When this was installed from Debian etch it all worked OK including the 'capchas' when I decided to set up a newer system on testing it does not. Thanks!! Frosty

Well since no one has any ideas I thought I would post this follow up from my own efforts, in the hope that it might help someone else. It seems that the captchas are actually working OK. The problem is that the browser (iceweasel) that I have installed is not displaying the artwork created by the captchas. I downloaded another php captcha called jhfcaptcha which is self contained and may be run as a script via Apache2 from my web site. It has exactly the same problem. It asks for you to input the entry needed by the captcha to do its job...however there is no box or any thing else that shows what I am supposed to type in. I have checked the following: GD is installed and working according to a test.php script that shows what is going on. Php is also completely enabled and as many functions as I can find are installed and enabled. I did notice that the mime-decode function is not enabled. I will try that today. In the mean time ANY IDEAS are appreciated. I also tried from another computer using XP and IE7 and the only difference was thate is a box with a missing image element icon in it and you still can not see what needs to be keyed. The more I see of this the more I think its a php issue are a graphics conversion problem.
