If you have Irfanview or similar, pull up a pic from your camera.
You will find an Info button at the top of the page - click it.
On the panel that comes up there should also be a small button at the bottom with EX info etc.
Click this and all the info on the pic itself, plus the camera model, exposure time, whether flash was used etc will be revealed.
Well at least it does with my Minolta Dimage E203...:-)
