Imagefield in views type "user"

Hey there!
I'm working on a view that needs to list fields that are partly in the views type "user" and partly in the views type "node".
How can i get them into one view?
What i need to do is to get a view with all the friends "flagged" with the flag module. But i need to use imagefield to present the profile image. Imagefield doesn't show up in type "user".
Is there any solution for this problem? I would be very grateful about any help!

Thanks honorfield
