anyway. There are a few different ways to see EXIFdata. With Windows you can download Opanda or do a search for viewEXIF. After downloading a program such as these you can then right click on a picture on the internet and as long as the information is still embedded in the picture, it will give you the EXIF info. There are some picture hosts that strip this info. So you wont be able to see every pictures info.
If you use firefox, there is a different application that you can dowload for that web browser.
For viewing your own pics on your own computer, you should be able to use the imaging software that came with your camera. With Vista if you right click on the thumbnail in your folder and click on preview that info should come up on the bottom of the screen.
