Although Raspberry Pi (RPi) is not powerful enough for heavy-duty image processing, you can still put it to some photography-related uses. For example, as an amateur photographer, I take a lot of photos when I travel, and I upload the photos to my Raspberry Pi at home which neatly organizes and keeps them safe till I get back home.
To turn RPi into a photo station, I opted for the Debian Wheezy minimal image. The only thing I needed to install was the usbmount tool which automatically mounts and unmounts external USB storage devices. Although it's possible to save photos on the SD card, I decided to keep them on a dedicated 16GB USB stick which usbmount tool mounts at /media/usb0. Since the minimal image comes with an SSH server enabled by default, I only had to configure my router to make RPi accessible from the Internet.
