Display Size and loading Lenna

[mayoricecream]

Hello,

When I try and get the pi to display the window in full-screen my monitor will turn black and stay black until the project breaks. When I hard code the resolution it works fine. For now I am just running the code with the resolution hard coded but any tips regarding this subject would be cool. 

I am also having another issue that could very well be a typo. When I try and get the picture of Lenna to come up I can see a opengl window opening up but the program output gives me a error until I break the program. I believe it has something to do when I draw the rectangle but I am not certain.
