Hi there. That stuff you are seeing is the contents of the png file, like
you would see if you looked at the png file in text editor.

I believe the solution is that you need to set your http headers to
appropriate values to display an image.

Try putting this line at the very top of your php:

Header("Content-Type: image/png");
