Easy Photo Geotagging in Linux with Prune

There are many tools out there that purport to simplifying photo geotagging for Windows, Mac, or linux setups. However, most of these utilities are designed to take tracklogs and synchronize them with photos that were taken with certain timestamps. For someone that doesn't have their camera set up this way, or who doesn't want to leave their gps on unless they are marking the waypoint of a photograph, this method doesn't work!

I tried a LOT of different software, but the one that finally "just worked" was Prune by Activity Workshop. With this JAVA software, I can open a directory of photos, open a GPX file and handpick which waypoints should correlate with which photographs. It also does all of that fancy auto-syncing stuff, if you start to get into that.

Hope this helps others like me.
