Do you mean geotagging? If so, this link might be of interest tips on geotagging photos in Picasa
I'm not sure how this would work with random photos downloaded from a site but......
First, I'll admit I was busy with other things while the newscast was on, but from what I understood the GPS information (latitude and longitude) are automatically digitally attached to photos made with a GPS equipped camera or camera-phone. I can't say if that is the case with all such cameras and phones or just with certain ones. They were talking about how people on such Internet sites as Facebook were surprised to find out that people knew EXACTLY where certain pictures of theirs were taken. Thus my concern about pictures being posted on certain threads here at CM. The reason for automatically attaching this information was apparently so that people on vacation could go back and see for sure where certain pictures were taken in case they forgot, and other similar circumstances.
Geotagging information is stored within the photo's metadata block, if I'm not mistaken. Some applications can read this metadata and use it, many older applications cannot as this geolocation data is a relatively new concept.
It might be possible to make a copy of a digital photo that excludes that geolocation (and other camera generated metadata) and if that copy is the one posted to an internet site, no one would be able to gather location information.
You're right. Someone using geolocation information could determine the whereabouts of the subjects in the photo for whatever purposes they have in mind: private investigators looking for marital cheaters, a stalker keeping track of where his or her object of infatuation has been, etc.
Geotagging has its uses but as with any other tool, its use needs to be thought out and appropriately turned on or off as the situation calls. Be safe.
