Hi all,
I have made a nice tool with excel that will allow you to create images on your 8x8 matrix very quickly.
You just need to make the image in excel and it will give you the line of code that you need.
I used ports functions with my LED matrix so the tool is based on binary numbers, so if someone uses another way I can modify the tool. 
Just follow this link and you will find the excel file:http://freepdfhosting.com/f16c70abab.pdf
