ID pics are pretty simple. Upload the image into your scraps(when you post a submission, there's a little check box that says "Scraps" or "Put in Scraps" or some such other nonsense. Once that's done, go to the UI. Follow:

My FA>Account Management>Profile Info

Once there, there's a box that reads "Profile ID". The dropdown will list all your scraps submissions. Select the one you want and click SAVE.

Viola.

Oh thank you so much! :D

No prob. I see you deleted my shout, haha.
