Your GET syntax is wrong, you should be using:
index.php?first=value&second=value
The way you were doing it you should see the second variable contained within the first value.

You can use any valid PHP code before or after sending an image header
so long as you don't inadvertantly output to the browser. I am not sure
what that error message means though, I'm sure someone who uses the
image functions more frequently could give you some clues.
