Is there an easy way to add new entries to existing EXIF data? I'd like to add my name for copyright reasons and categories like "friends", "business" or "nature".
It's very important for me that the file date and time is not touched at all.

Well, I know that I can do it manually for each single picture or while downloading new pictures but I have thousands of existing pictures that have to be categorized.

I have played about with extracting EXIF data from files using the Python programming language and the EXIF module. To do the opposite (i.e. write data into the files) requires a different module. I think that there is something to do it (I forget what it is at the moment), but didn't actually get round to sorting it out. Perhaps someone else has tried this route?

Edit: If you want to add the same text to a group of image files use the free Exifer. More discussion on this here: http://jalbum.net/forum/thread.jspa?thr ... 7&tstart=0 . Exifer can be found here: http://exifer.friedemann.info/ .
