I'm not sure why no body has answered you yet.
There are two general ways to upload pictures of your file:
1) Download "Screensnapr". Follow the instructions and you should get a link to post onto your thread.
2) Use the "prt scr" button on your keyboard. This will copy your whole screed. Afterward, paste it to "Paint", edit out what you don't need, and upload it to "Imageshack". Imageshack will spit out many links. you want the forum one. Cut out the juk they add and slap some image tags on it. you're set
good luck with the sales!
