1. Start up a custom game on your map by yourself.
2. End the game after about five seconds.
3. Go to theater mode and pause the film of the game you were just playing on.
4. Take pictures. Around 10 is a good number depending on the map.
5. Go to your computer and go to Bungie.net
6. Go to your profile and click recent screenshots.
7. Click on the screenshot you want to use and when it's a large image in your internet browser, right click and save. Repeat this step for every picture you're posting.
8. Make a Photobucket.com account, it's free. or go to imageshack.us
9. Press upload and hold ctrl while clicking all the pictures.
10. Click open or upload (whatever button is on the bottom right of the upload, open, save popup window.)
11. Hover your mouse over the uploaded picture below and click on the area called IMG code.
12. Copy that, ctrl c.
13. Paste that, ctrl v into the thread and there you go!
