The previous code seams fine to me.

What version of GD are you using? If it's 1.6, as said in PHP docs

"Note:  Since all GIF support was removed from the GD library in version
1.6, this function is not available if you are using that version of the
GD library."
there wont be gif support.

Have you tried the same code using other formats, like jpeg, png?

Try sending the output to a file( use the second optional parameter to
imagegif, imagejpeg, etc) and check the file size.
