I have added a new article to the Wiki that explains how you can use [FwTools] to create GeoTIFF files, which you can use for your photo scenery. There might be other tools to do such tricks, but I am familiar with FwTools as I use it at work. And besides that it is a open source project, which means it is free to use. So therefore I decided to make a little article about it.
The article describes how you can add positional information to an image and how you can reproject it to WGS84 if needed. Hopefully the article is useful to some of you and I will try to expand it with other useful information when I find some more.
