Step 1. I search Google Images for a picture of milestone player.
Step 2. I download that picture, then crop it to the max size. I'm on Mac and all I use is Preview or sometimes Grab. If you're on Win, I think you can use one of their paint programs.
Step 3. I upload that picture as my avatar, then take a screeshot of the post. Again, I crop that or just grab the exact picture I want.
Step 4. Upload that picture to my Photobucket account. Voila.
The great thing about taking the screengrab of the milestone is that you can instantly start posting away without worry of "losing" the milestone. If all of this sounds extremely tiresome just hit the old Prnt Scrn button on your keyboard, open a document and paste the picture into the doc.
