Hi Bernard, Welcome to the CiC forums.
The EXIF data is usually visible for your own shots on your computer when they are open in an image editing program.
They may also be available as File Properties as Denise's third image (in first post) demonstrates.
For images on the internet ...
I use the FireFox browser and there are Add-ons available for this to view EXIF data.
If you don't use FireFox, all is not lost, visit this site; http://regex.info/exif.cgi, then paste the url of the image into the top box.
You can usually get the image url by right clicking and selecting one of the options there Copy Image Location (FF) or Copy Shortcut (IE).
Cheers,
