I use clipart from Google in my class worksheets and presentations and I know this is ok as it's for educational use.
However, I've had an idea of starting a blog and including packs of worksheets and videos and so on, that teachers can pay to download and use. However I'm concerned about the images - I have used hundreds if not thousands over the years and I don't see any way in which I can use them commercially without getting into trouble?
Does anyone know the relevant law on this - I have searched but there is so much conflicting advice out there. Does anyone have a teaching resources blog/website, and if so how have you managed to deal with the images issue?
Thanks
