Gallery2 running fine. The other day I wanted to enable Captcha to increase performance. Captcha requires the gd toolkit, so I installed it and it's libraries. All went fine. In Gallery2 site admin I installed gd and it said I should configure it, so I clicked configure. On the configure page it says "GD library version: You don't seem to have the GD library available on this PHP installation." and refuses to activate. As far as I can tell the gd package, its tools and libs are there. I'm at a loss here, can you help please to solve this problem? Thank you. |

First you need to increase your memory limit to 32MB
FAQ: PHP memory_limit - Why do I get the error Allowed memory size of Xxx bytes exhausted?
Second, GD support is not loaded into PHP. Contact your host about that.
And honestly, I wouldn't even bother with GD. The exec function isn't disabled on your server, so I'd try to get either ImageMagick or NetPBM installed and working.

Thanks for replying.
Done. Added it to the .htaccess in.../gallery2. I don't quite understand why this is necessary though, as I did not get the errror "Allowed memory size of Xxx bytes exhausted"??
Kinda' figured that out myself. ;-) I'm hosting my own server, ie I have root access, and whatever I do I can't get GD loading into PHP. Figured you could give me a hint on how to fix this. Not sure how to proceed with this otherwise.
I wanted to use Captcha, which requires GD. Following your hint above, I won't be able to use Captcha, as it requires GD. Am I understanding it right?
FWIW, NetPBM and ImageMagick is working fine on my Galleryinstallation.
Edit: Found this: http://codex.gallery2.org/Installing_an_Image_Processing_Library#GD, but I don't feel it's quite relevant for me, as I run linux. Also found this, http://www.libgd.org/FAQ_PHP#How_do_I_get_gd_to_work_with_PHP.3F, but here they speak of re-compiling php, which is something I'd rather not do as I don't have the knowledge. 8-/

Or maybe I should just forget about Captcha and ignore GD altogether, as there are thousands of articles describing all kinds of small hells trying to compile gd-support in php. I'm leaning towards this.. 8-}

Possibly. What Linux distribution? Debian? Sure. Something else, maybe.

looks like it's just yum install php-gd, then restart the web server.

Thank you, it worked!! I can't believe I missed the above link, after all my googling. Php-gd installed now, dito the gd-package, dito the Captcha package.
A thousand thanks, you rock bigtime!!

Captcha doe snot increase performance but is increases security slightly. Perhaps that is what you meant.
