found out that the database is an excellent source of random numbers if you
are stuck doing <img src=img.php...>

Also discovered that my host's apache configuration might be load PHP as an
..SO module under UNIX, therefore PHP *might* not get its own PID. If UNIX
..SO's are anything like Windows DLL's, only Apache has the PID - PHP
wouldn't even be a child process - it is simply allocated a chunk of memory
for its functions to load in.

If this were a CGI, then it would definitely get its own PID, but PHP.net
doesn't recommend this method of configuration.

To be honest, I haven't tried getmypid() after discovering that the URL on
src= needs to be unique so that the image isn't cached and therefore
duplicated. Now that I've got everything working, maybe I'll give it one
more go just to find out.
