You can do what I did:
1. Press PrtSc (Print Screen)
2. Open paint or GIMP or Photoshop (I highly recommend GIMP, it's like Photoshop, only free)
3. Paste
4. Make modifications
5. Save as .jpg
6. Go to imageshack.us or tinypic.com
7. Find the picture you saved and upload it
8. Click on the proper formatting (On imageshack, you want Forums 1, on tinypic, just choose messageboard)
9. Copy and paste into your post
10. Comment me on how stupid I think you are.

. JK!
