I don't know how to check to see if "composite" is installed.
I did install what was mentioned on this page: http://www.photopost.com/howtoinstall-php.html

But I have no way (that I know of myself) to check and make sure each one got installed.
I can upload an image, but it doesn't slap my watermark onto it. Is composite one of those things I installed from that page posted above and if so is there a way to check to see if it installed properly?
If not, can you direct me to where I can find "composite" and instructions on how to install it on a Linux server?
