Since Google created its new image search, I've been really frustrated. To do an advanced search, you now have to scroll to the bottom of the page, go back to "basic search", and then choose advanced search. Typically, I look for this feature because I want Creative Commons licensed images that can be reused on either my blog or the EdTechTeacher blog. While I feel like I heard about Photo Pin before, I'm glad that I rediscovered it today - thanks to Richard Byrne at Free Technology for Teachers. This is a great resource for searching for images licensed for reuse.
Props to Adrian D. He supposedly has it on either his office or classroom door. I found the link in his response to a student's query about it on his blog.
