I agree it is very useful to use pictures when explaining something. The most typical example for electronics.se is clipping schematics and diagrams from data sheets. However, by the strict letter of the law, a data sheet is copyrighted in its entirety. It's probably never a real problem, because data sheets are also intended to be promotional material, so the more a certain manufacturer's data sheet gets mentioned, the better is is for them. But still, I would like us to be on the safe side. Thus, my question:
- Is it o.k. to clip information (pictures, tables, whatever) form a copyrighted source?
And a related questions that may lead to an answer:
- Is it o.k. to clip something short (just one diagram, maybe), as long as you mention the source, because it is covered as Fair Use, as linked in an answer to this question on the stackoverflow meta?
Even sources like wikipedia need to be considered, because, without being an expert, my guess would be it is o.k. to use freely licensed material only as long as you mention the author or source.
I have the feeling that the most troublesome feature of the site could be the one that clips entire pictures from other websites, because the way the feature is designed, the source is not linked automatically.
