Flickr

I think Flickr would be handy to use for images-possibly an alternative to the go to Google Images.  Time would need to be spent on what part is "free" access and the permissions and restrictions piece.  This could be the basis to a good lesson tied into plagarism, copyright etc.   I also think it would be good for discussion points around social studies, science etc. when you need more authentic examples  to provide more background information for project work etc.  I happen to love different types of architecture.  I am particularly fascinated by bridge architecture, thus my choice of the Golden Gate Bridge in San Francisco which so far I haven't been able to see for real!
