The iPhone now has the ability to add the location a photo was taken to its metadata. Flickr’s been able to handle this for a while, but you had to map the photos manually. To enable it to understand the location data, first you have to authorize it to “Import EXIF location data” in your Privacy & Permissions settings. Unfortunately, according to Macworld, this data isn’t included if you email the photo directly from your iPhone, but if you copy it to your computer first, then upload it, it should work. Emailing a photo directly from the phone also resizes it, though, so it’s better to upload them from your computer anyway. I’m hoping that Flickr will release an iPhone app at some point.
