I have a huge and growing graphics file collection, which I store in the folders. I wonder if there is a special tool for designers to tag and search these images. Editing is not necessary.. For instance, I would like to find an image, which contains cats, or only white/black colors instead of browsing my 500gb folder structure manually...
Google's Picasa is free and will let you tag your images and search for colours. It can even use face-matching to recognise who is in your pictures. It does not support vector graphics though, so if you really need that, you might want go for Adobe Bridge. (As suggested by JFW) It's not free though and comes with the Creative Suite 5.
