ImageJ is one of the older free, open source image analysis programs. Alone, it's not that powerful; it's real strength is the vast array of plugins for it. It runs on Windows, Mac, and Linux.
FIJI is probably the best distribution of ImageJ for routine data analysis. It comes with a vast array of plugins already installed and ready to use and has an automatic updater so you always have the latest versions of them.
Micro-Manager is a microscope control package that is built on top of ImageJ. It's developed at UCSF and is very powerful; we use it to control the Spinning Disk Confocal in the Nikon Imaging Center.
