Versatile Encoder allows you to encode your own videos into good quality DivX files. The input can be a sequence of files (as generated by blender), a single file (if you want to recompress something), or a VCD (if you need to back up a movie). This piece of software tries to guess good defaults and to help the user in making choices.

A lot of stereoscopic cameras use the .MPO format to store two JPEG images, including the Fuji W1, W3, and a few 3D camcorders that have a still mode. It can do two things for you: it can separate out the image files into a left and right pair, so you can process them or do whatever you want with them, or it can create an anaglyphic image (the ones you need coloured glasses to view). It is simple to use from the command line and takes wildcards, so you could process a whole batch of files with: mungempo *.MPO.
Gallery Mage is a client side photo gallery management system designed to work with online gallery display scripts such as SPGM. Using Gallery Mage, one can select, caption, rotate, crop, resize, and upload photos taken with a digital camera to an online photo gallery. The rotate, crop, and resize parameters are stored as text data with the images, and the operations are only performed on a copy of the photo while exporting, thus preserving the original picture files. Gallery Mage provides abstraction from the online display software.
