An interesting module (especially the history of copyright) and one I am most definitely not an expert in! I have a basic understanding regarding copyright in schools but if I'm unsure then I'll check out the Copyright Licensing Agency schools page http://schools.cla.co.uk/ or the CILIP website which also has some useful information about the wider remit of copyright.
I do think schools have more flexibility regarding the use of materials for educational purposes. That said, it's a nightmare trying to get students and staff to attribute correctly and the former just do not understand the concept of plagiarism very well at all. I always attribute any work I use ... referencing in text, using bibliographies, crediting images so try and lead by example. I also deliver sessions on these skills but I am certainly not responsible for the work produced by 1200 students. Not sure how you'd check it for copyright legislation without looking at each piece which would be impossible. I'm also not sure who is responsible for ensuring the school adheres to copyright law, I suspect it may be the bursar but I know that even the reprographics department doesn't check what it is asked to photocopy to make sure it's legal.
The other aspect of this module was regarding ownership of work I've produced. Most of what I create is done in my own time; some of these resources are specifically for use within school, either promotional material for the library or for lessons, so I guess legally they belong to the school. Other material has been created for personal projects that are not connected with the school but I have adapted and used them within the library. I consider these to belong to me and am "allowing" the school to use them free ...improving the service and providing added-value!
As directed, I have explored Creative Commons and Public Domain images online. I signed up to a CC website only to be met with two choices - download my own photos or pay to download one on the site - neither of which I wanted to do! Thus I then searched for copyright-free images and have downloaded one as requested, details are: http://www.copyrightfreephotos.com/ Canary Wharf 02
