As long as your settings allow for it, your phone attaches GPS data (lat, long) to your photos when you take them. Make sure your wifi is enabled for best results.

How to enable for photos
Use your standard uploader (I use Image Capture, which is built into OSX) to get these images AND their attached geo tags (part of what’s called EXIF data). If you edit or crop your photos, be sure to keep the original file for reference, as many editing and uploading softwares remove EXIF data for your privacy.
ADDENDUM: I thought GPS data would show up in the photo’s info, but I found that (at least on my Mac running OSX 10.6.8 [I know, it’s 2016, but I really hate OS updates]) I had to open the photo in a program to see the GPS data. I used Preview as described here. This article gives the same directions for Windows, as well as a rundown of mobile apps that give you the same info on your phone.
Happy exploring!
