The files were created in Photoshop, and can be opened by Preview and Safari. The files can also be opened and edited in Gimp 2.4.6 (gimp-2.4.6-1.fc8) running on Fedora Core 8. Precise error message from Gimp: {{{ PNG image Message Error while reading '/Users/darren/Desktop/background_img.png'. File corrupted? GIMP Message Opening '/Users/darren/Desktop/background_img.png' failed: PNG image plug-In could not open image }}} If I start Gimp from a terminal and then open the file this error message is printed to the terminal: {{{ libpng error: x[DA][94][FD]: invalid chunk type }}} Running: {{{ Mac OS X 10.5.4 MacPorts 1.6.0 gimp-app @2.4.0 aqua/gimp-app gimp-user-manual @0.13 graphics/gimp-user-manual gimp2 @2.4.5 graphics/gimp2 libpng @1.2.30 graphics/libpng }}} -- Ticket URL: <http://trac.macports.org/ticket/16371> MacPorts <http://www.macports.org/> Ports system for Mac OS

Try upgrading libpng and see if that works. -- Ticket URL: <http://trac.macports.org/ticket/16371#comment:1> MacPorts <http://www.macports.org/> Ports system for Mac OS
