Viewing geotagged photos in QGIS volcan01010blog 2018-11-22 | QGIS 3 has built-in functionality for viewing geotagged photos. This video shows how to import them, to add a base map for context (e.g. Bing maps) and to set tooltips so that you can see the image when you hover your mouse over the point location.It also demonstrates that if you take geotagged photographs of notes taken in the field (e.g. as part of geology or ecology projects) you can also view them in the context of the map. This is a very powerful tool.
