Extracting image metadata of multiple files

Right-click on a jpeg in XP click "summary" tab and there are metadata
fields. My questions are:

How can I extract this data for each jpeg?

Is this exif data is it some proprietary MS format? I see it in my text
editor...

If I have hundreds of images is it possible to "program" this ie. loop
and put data in a flat text file?

Thanks very much!

Yes. The following functions would cover most of this.
