In Myspace, hover your mouse over your main profile picture and you'll see a link in your browser at the bottom of the screen. Mine looks like this:
http://viewmorepics.myspace.com/index.cfm?fuseaction=user.viewAlbums&friendID=65435510
At the end of the link you see your friendID. Mine is "65435510".
If that doesn't work, right-click your profile pic and choose "Copy Link Location", then paste the link somewhere you can read it, like the address bar at the top of your browser.
Copy (or write down) the number, now you have it!
