Upload of portrait gives me error

I've moved my site from my developer server to a production server, and now I get an error when I upload a picture to a profile:
Error occurred during the moving of the uploaded file. Method: Move
As far as I know the owner of the files / folders are set correctly, and the rights should be.

Hmm, ok, I've changed the permissions to 777 on the images/comprofiler folder, and that solved it.
