I found the problem. For reasons I don’t know the gd library didn’t get compiled with jpeg support. I actually had to recompile the jpeg library first (it didn’t include the set_jpeg_defaults() function call for some reason), then the gd library, then PHP and re-install PHP and now everything works great. Thanks for the help!

Ido:

You have to insure your directory structure lies inside a www directory. To get this result, say your web directory is…

/something/HTTP/…

then do

ln -s /something/HTTP /something/www

In your case, your problem seems more complex… for example, it tells me the image is at….

/opt/www/dubrawsky_org/tmp/hn_captcha_075efa.jpg

But I’ve tried the following URLs and can’t find it…

http://www.dubrawsky.org/tmp/hn_captcha_075efa.jpg

http://www.dubrawsky.org/dubrawsky_org/tmp/hn_captcha_075efa.jpg

So, I’m not sure what you are saying when you say that the “the DOCUMENT_ROOT is /opt/www/dubrawsky_org”, if so, the first URL should work. Have you set permissions right?

I ran into the same problem with ImageMagick, and installed this instead. Nice. Works cleanly. Agree that it would be better if I could use a system TMP directory rather than a WWW accessible one.

What exactly did you do to get around the problem with the directory structure? When you go to the URL for my website (http://www.dubrawsky.org) the DOCUMENT_ROOT is /opt/www/dubrawsky_org and captcha doesn’t seem to want to work. I’m interested to know how you got around the problem.

Nice to see you’re using captcha!

Thanks for your suggestions.
I didn’t want to change the original hn_captcha class. That’s why I used tmp and ttf folders that way. But you’re right:

Some other people have told me about TTF slash and tmp directory.

TTF Folder can be (not tested, but should work) in any directory readable by Apache/PHP, but TMP directory must be inside the apache published directories, because the image is served as a jpg.

I was thinking of showing the image “on the fly” with a php script, so the TMP could be anywhere in the filesystem (and not into the www) or even not necessary at all.

If you’re interested, I will tell you, and again, Thanks.

Great to see your comments are back! They’re what make blogs more interesting than plain old web pages.
