Hello,
I have installed ImageMagick on my linux server, and checked that it works OK from the terminal. I then entered the paths to mogrify and convert into the UBB control panel, which in this case was...

/usr/local/bin/convert
/usr/local/bin/mogrify

I then selected to use ImageMagick on the gallery section of the control panel.

However, when I try to post new images to the gallery pages on my forum they just appear as broken links. Checking the gallery directory the image files are not being added there either (the permissions for that directory and all enclosed directories were set to 777 as instructed). Any ideas what is going wrong?

Thanks,
Phil

First thing would be to test imagemagick. You can the ending url to this while logged in as admin to test it:

ubbthreads.php?ubb=captcha&t=im&test=1

OK tried that, just getting a blank page at the moment

...though when I tested imagemagick from the command line I could generate an image fine. I would use GD2 instead (which I was using fine in 7.2.2) but since upgrading to 7.3, using GD2 I keep getting a message "fatal error: Allowed memory size of 33554432 bytes exhausted" which I have noticed a few other users posting too. Even though the files were well under 33554432 bytes and the permissions allowed for fair sized images.
Anyway, I would rather get ImageMagick working than GD2 if possible.

It's total memory being utilized at the time of execution via php; you'll want to report it to your webhost so they can increase the value.

I have a dedicated server with my webhost which has full root access, is this something I can adjust myself?

Edit your /etc/php.ini, change max_execution_time (i think is what it's named) and change it to 35M or so? Depends what it is now...

Gizmo, I edited the following line in php.ini: memory_limit = 36M (was 32M)

No good.

Then I edited the following value on php.ini: upload_max_filesize = 35M (was 2M)

No good either.

Still getting this message:

Fatal error: Allowed memory size of 37748736 bytes exhausted (tried to allocate 12288 bytes)

Looks like you need to bump it up a bit more. Your memory_limit is 36M, and it's trying to allocate a bit over 37 megs.

37748736 <-- is exactly 36M (1024 remember?)

but regardless, it needs an increase..
