Photobar is a nice Drupal module which features automatic uploading of images and galleries creation. It also has some exif support, such as taking orientation.

I wrote a little patch for the 4.7 version to also calculate latitude and longitude from the exif data, if any, and set it as the node's location.

Here's the patch: geocode.patch.

Later edit: the patch has been commited. Download the module instead of this patch.
