Yeah for sure upload a pic from your Iphone so everyone can see your metadata and get all the info needed to find out where your at better than a IP address
So you probably know by now that when you take a picture with your smartphone or with your digital camera, it stores a lot of extra information about the picture called metadata. This is called EXIF data and it can tell you what camera model took the picture, the date and time, the shutter and exposure settings, the location, and lots more. There are lots of ways to view the EXIF data for a photograph and in this post I’ll walk you through the various tools you can use on an iPhone, Android phone, on a Windows machine, or on a Mac
