If you reference a blog post or webpage, can you also legally use an image on that webpage in your reference?

This is an area that many people misunderstand. People commonly confuse this with school rules about plagiarism, where citing a source is important.

In copyright law, giving me credit or stating that you claim no ownership in the material is meaningless, but you see it so much on YouTube that people start to think that it means something.

If your copying of my material is an insubstantial amount, that is considered fair use and not a violation of copyright law. See my source for the fair use standards that courts use. Keep in mind that these are the standards applied when your case gets to court. If nobody sues you, then you're fine.
