Rotate images problem

[DemoDoG]

Since I use xfce4.6 I installed Ristretto as a image viewer. It seems though that when I rotate images it does not save this automaticaly to the files so next time I view them they are back in original. Is there some way to get Ristretto do this or can you recommend another fast imageviewer that does the job?

gqview can rotate the image and save the rotated image to the same file automatically.

Yeah thanx, I also found Gpicview which seems to have a nice simple interface as the one in Windows.
