Passing on some information, it may be useful for someone
For some time I've used a free program called Exifer to copy image data from image to image because Qimage does not do this when images are converted.
However, development of Exifer has now ceased and I needed something else. The Exifer site recommended PhotoMe but that is not fully developed and does not yet import/export data.
The other program recommended is ExifTools. This is a command line program which is ok for those who understand how to use such applications.
It would be nice if there was some way of using it from within Qimage.
Fortunately, someone has produced a GUI fro the program that enables many of the features via an easy to use interface
You can access the downloads & instructions here: http://freeweb.siol.net/hrastni3/foto/exif/exiftoolgui.htm
I have attached a screen shot of the GUI below.
It's an easy program to use and unlike Exifer, will copy from raw images.
