EDIT: Now that I'm going through ALL of my files, moving into my new machine, I've added some more images to the widget. Enjoy!
Box.net provides free online file hosting (and more), which I use for some items I've posted to my website and blog, has a new little widget for posting files to your blog or website. You need to have Adobe's Flash Player installed, but that's what makes this really neat... [Does anyone still say that?] You can preview images and video, right inside the widget! So, try it out, already!
I'll try to get something more interesting uploaded.
Until then, Happy Holidays!
