Checkout this flickr collection: Upload Video. It’s a tutorial on uploading video to the Internet Archive, etc… but the cool thing is this: the tutorial is saved on flickr!
It looks like someone turned powerpoint slides/other graphic files into jpgs, and posted them in order in his flickr account – saved as a colleciton. From there, you can view the collection as a slideshow.
Try it out – what a great and unique way to use flickr!
