I have had to look over a couple days at Flickr. I think this will be a powerful site as I start to work with my students on collecting images for their projects. Right now they are learning to use Google Images and I am going to start teaching them how to use Flickr.
I took a couple pictures of my media center and uploaded them to an account I created in Flickr and I was suprised at how easy it was to do.
The next challenge is getting them uploaded to here and I'm still working on that. I did get it to upload from my computer but not from Flickr yet.
