I have been meaning to use a Photo Management software for my Photos. I had been fooling around with Picassa on Windows, but somehow I just don't feel like using it on Linux.
Did some reading around and kind of figure that digiKam would be the way to go. There are other options too, but at the moment, I think I will try out digiKam.
One prinicipal reason, is that digiKam does not create external tags, rather it writes the tag into the metadata of the photo. So this way I might be able to get out of creating tags for the photos, when I upload them onto flickr. So then digiKam it is, at least for the time being.
