I have been searching for images to use on presentations for my class but keep stumbling over the thorny issue of copyright. However the wise and generous teachers I follow on twitter had lots of advice for me - @johnskelleher recommended Wylio.com which has a great collection of creative commons pictures you can use with without worry. I have signed up for the free account so look out for exciting new grahics! Thanks John!
I also got lots of other suggestions which I will also be exploring. Thanks twitter pals!
