Woof.

I'm surprised it took 3000 characters to become a problem... :-)

You MAY want to try your HTML with src="createimge.php?wp=..." instead
of the single quotes.

Yeah, HTML 4.0 or whatever didn't care, but that new-fangled XML HTML
crap it matters, I think.

In the script that writes out the HTML, don't write out all those
numbers in the URL.

Stick them in a database table, or put them in a session, or if
speed/performance is a Big Issue, and those can't hack it, stick them
in Shared Memory.

http://php.net/shmop

Then you can pass a small identifier like an ID from the database, or
whatever you want for an array index in your $_SESSION, or a path and
integer for the shared memory.

If shmop isn't fast enough, then you're in real trouble :-)
