I loved this assignment from Associated Content--a slide show of Autumn Leaves. I didn't have enough of my own pictures so I asked some of my friends on Facebook. It seems no one was willing to part with their photographs. Not to worry, upon reading the rules about uploading slideshows on AC I found out that you could use images from Commons Wikimedia. Awesome site--lots of pictures in public domain (you still need to read the copyright laws) or simply find out what the photographer wants (like credit and all that).
