There is a bit of a security risk when one uploads pics taken by a smart phone, like the iPhone or Android, or more rarely, from GPS enabled cameras.
You can watch a video about it here
I use Google Chrome browser and by installing the EXIF addon, which is available for most major browsers, I was able to see from JP's pics of his first swarm, a Google map of the location. I was also able to see where AllenF's Jabba the Snowman was made and Bix's frame anomaly was taken. All with addresses and some with street view. Among the multitude of metadata that smart phones store in the pic, is the latitude, longitude, altitude and compass direction of the pic.
Take a pic of your secret apiary with a smart phone and upload it to the web, and it isn't a secret anymore.
I believe the safest tact is to download a EXIF editor and edit the lat and long out of your smart phone pics before you upload them to the web.
