> EXIF support - EXIF preview image is gone when saving

Hi Peter,

many thanks for continuing the development of PMView for OS/2.
I've downloaded the new release and was surprised that the most important feature (for me) I missed so far is now implemented in almost exactly the way I was hoping for.
I'm talking about the EXIF support for JPGs from digital cameras.

Many programs only keep the EXIF data without adapting them to the changes you did to the image. I've seen that PMView will adapt the values (checked out the size and the orientation so far) according to my changes. GREAT !!!

But I also figured out that the preview image that is part of the EXIF data is gone when saving. Is there a way the recreate the preview out of the image data like for the thumbnails ?
If not, this would be a great enhancement. (So far I'm only aware of one tool that is able to do that, Exifer. But that's a Windows program and I'm working on OS/2 sad.gif )

1.) Modifying the EXIF data would sure be nice. However, this requires much planning (deciding on what to allow for update and to what extent. You don't want to let the user mess up the data by accident).
2.)Updating the time stamp and application should probably be optional. (That's why I decided not to do it in this version). The GPS data should NOT be updated, should it? AFAIK, the GPS data indicates when and where the photograph was taken. Updating with PMView doesn't change those facts.
3.)I can easily add Iptc support. I just need to get the specification for that. (I usually implement from the specification, not from existing source code).
