I have had some trouble myself with the io pins when working off the official board, one thing that was suggested to me is decoupling capacitors at the power and ground connection at the chip. I have been using .01uf ceramic discs. Your picture appears to be near identical to the setup I use (other then the caps.) and blink works fine.
** After zooming in real close it looks like the resistor for the LED on pin 13 is not plugged into the right row.**
