OT I need JPEG or TIFF image file which contains GPS info

I am looking for a few image files that I can use for testing, for reading and writing GPS exif information for these files. The only reason I am asking on this forum is that I will be adding this for apple scripting. If somebody could explain what some of the information means and how important it is to have available that would also be great.

If you can help me could you please e-mail me on: ktam at yvs dot eu dot com
