Hi, I need the answer to this question too!!! I've been trying to find some sort of installation instructions for shared hosting and nada!
This would be very useful for me on several of my sites if I could get it installed. I have a nice little script using system functions and pnmscale, cjpeg, etc., that only works on one hosting company's site and that hosting company sucks. I want to be able to use it on my preferred host. The system function works there, but there's no netpbm.
Can anyone give instructions on how to install netpbm on shared hosting? I uploaded the files, but don't know if that makes it 'installed' or if I need to do something else. Plus, don't know if I need to do something to my command in the script to tell it where to find the pnmscale command, etc.
Help?
