In fact, if you use Chrome there is an extension...EXIF VIEWER by from KK Zhang that works great. Just hoover over the photo and a information strip shows up at the very top of the photo and it gives some exif info, such as camera, settings, etc. If the photo is GPS tagged, it will add a red box at the right side, click on the GPS red box and it takes you go google maps with the location.
If you use IE, then a program called PhotoME is available, just right click on the photo and it opens a box with all the info.
Most, if not all, smart phones GPS photos (a lot of people don't know that
), some smaller range finder digital cameras come with GPS loggers embedded into the camera. With larger DSLRs they offer devices that plug into the camera (what I use) to log GPS locations into the exif.
You can strip the exif information in photoshop (or other products) if you want too. I leave it in most of my photos since friends like to view the locations on google or other maps.
