Dude - that works fine!
can you check your code - make sure you havnt got any white space at all
before the php starts in ANY file, and then check that you've got ALL
erros being reported (because you might have the error cant send
headers, output allready sent at line x) which will prenvent the header
being sent and then you dump the image to the screen which is the random
wierd characters (that means the image create functions are all ok and
installed, and you have an image object or similar).
my code was simple <?php {your function} makepie(10,100); ?> NO
WHITESPACE NO BLANK LINES NOTHING.
(ps you might even have a php include in the php file (php prepend or
something?) which might be inserting a space or a newline or ending
headers or something. Look at error_reporting() or similar in the manual
to turn error reporting on for your script.
Hope you find the bug, thats quite a nice function you have there.
