vi.sualize.us - del.icio.us for images

"vi.sualize.us is a social bookmarking website for visual contents — vi.sualize.us (read visualize us) allows you to remember your favorite images around the web, and share them with everyone."

If delicious is for tagging & sharing web-pages, vi.sualize.us is delicious for images. Easiest way to use is with the Firefox extension which installs on the toolbar. Just activate - add image to vi.sualize.us - click on the image you want to "save" & a thumb-nail is saved in your vi.sualize.us account. (Yeah, I forgot, you need to register). Tag the image when you're adding it. And you'll get this:

Why use it? Well, if you're working in education / e-learning & use a lot of Creative Commons images in your materials, it's desirable to acknowledge the source. Necessary even. (If you're using copyrighted images, well, stop reading now, this will be of no interest or concern to you).
Scenario. Find a "nice" image on Flickr, save it locally, upload to website / blog / whatever. Of course, you saved it as 2pussycats_playing.jpg & you can't remember the where, when or from whom. Tag in vi.sualize.us & you don't have that problem. And you can share your bookmarked images with your colleagues. (It's called collaboration).
And it's free. Highly recommended.

On the subject of Creative Commons images in Flickr, the advanced search option does allow searching for images available under the various flavours of the CC licence. Neater option is FlickrCC which again comes highly recommended. Use both & you won't have to bother about the copyright police ever again.
