AddType defines the mime type of file extensions. mime types are how
the server knows the difference between images, plain text and other
files. This information also carries over to the browser so it is
able to display the information correctly.
I believe the original problem was that AddType image/png .png
occurred before you told Apache to parse it as php. I gather that it
defaulted to the first one defined.
In any case, defining the content type from within PHP is the best
option in this case. It prevents real pngs from being parsed as php.
