EXIF is a data chunk embedded inside a JPEG or TIFF. It is used by nearly every
digital camera manufacter out there presently.

The data is usually a whole lot of parameters from the camera
(fstop/focallength/exposurelength etc.) Also there is a thumbnail
created by most cameras embedded inside the file (your camera uses this
for the thumbnail directly), and there are a few applications that use
it for the thumbnail as well (Photoshop/Paint Shop Pro on windows, not
certain about linux).

I'm told that WindowsXP has native support for reading EXIF data inside
explorer, and shows the information in the status bar.

Here are some example images of mine, with a small subset of the available
info displayed below them.
