[gentoo-user] {OT} Remote image editing (crop & rotate)

[Grant <emailgrant@gmail.com>]

Each ripped CD in my music collection is accompanied by a high
resolution scan of the album's cover.  There is a new plugin for gmpc
that displays that cover art at full screen on my HDTV.  As the huge
cover art images appear on the TV, I notice one or more sides that
need to be cropped, or that the cover needs to be slightly rotated.
I'd like to be able to edit those images as I notice problems with
them, but I wonder if there is an easier way than scp'ing each image
to my laptop, opening it in gimp, editing it, saving it, and scp'ing
it back to the HDTV system (especially sshd_config AllowUsers only
allows my user and the user running gmpc is different).

Any ideas?  imagemagick comes to mind.  Is there a script or even a
GUI I could run on the HDTV system that might be able to crop and/or
rotate quickly and easily?
