I spent a long time hunting down a mysterious bug. Some sets were working with this, while others were not. I finally realized the problem was that some set files had trailing spaces after the PHP code, which introduced content into the script, which stopped the ability to modify the headers. This problem never happened in Game Courier, because Game Courier writes the graphic image to a file instead of changing the headers of a script to turn it into a graphic image. So, if a set is not working with this, it may need to have trailing spaces removed from its file. If you're not an editor, and therefore can't fix it yourself, then please let me know of any set you find this not working with.
