Your PNG image is corrupt, it has a \n character instead of \r\n, (byte position 5) typically a problem arising from FTP transfering a binary image in text mode from Windows to Unix.

Before messing with PHP, you should check simply that the image is OK, eg adding the .png extension, placing it in a visible folder (in the web server) and browsing it.
