If you download photos from your smartphone to the internet, the GPS device in your smartphone also downloads geographical location information along with photo information. This enables viewers accessing your photo data to pinpoint your exact location. This might not be something you want.

Smartphones differ, but this GPS data can be disabled. This is an image heavy site because of the gunporn we want to share, but consider the above. I am told some digital cameras also record GPS data.

I got this information from my former company XO. I don't know anything more about it, but if I find any related printed material I'll post it.

You are correct. Here is an example. I just took a picture of this demon dog(he will take control of your mind if you stare into his eyes to long). Here is the information available from that picture.

I removed the information from the picture before posting it online and also changed the geo information that I posted, but I can verify it was accurate to about 10 feet. You may not want this information shared, and you can set the geotag setting on the camera so it won't include the info, but it can also be very cool when you can't remember where you took a picture, it remembers for you.
