How to use image metadata?

Internet research is failing me. Does image metadata impact my website SEO? If so, I'm having a hard time learning where and how to use it to improve my rankings.

Just using windows, right click, details: I can access Title, Subject, Rating, Tags, Comments, Author, and a lot more that don't seem useful.

Should I put a link to my website in any of the fields? What if it's an image that's actually going on the website?

Which field or fields should I include the target Keyword I'm trying to rank for?

Any other suggestions?
