Add Photobucket pictures to Myspace comments
If you don't think your own photos are exciting enough, you can also use Photobucket's "Find Stuff" search feature from within Myspace's comment editor. This allows you to find totally cool animated icons, funny (while relevant) seasonal pictures, or pictures from other users' albums.
As Mashable points out, for some reason Myspace doesn't automatically log you in to Photobucket. At least the second login is inline and doesn't require a new tab or window to go hunting for a picture URL.
