Tips for LinkedIn?

I’ve never made a LinkedIn before but here are my questions: - Do you have to put up a photo? Should it be a professional level (photographer) photo? - Is it worth to use LinkedIn if I don’t have a degree? - I have a high school diploma and about a years worth of experience in the HR world (recruiter/HR Admin) what do I look for or how do I market myself if I don’t even know what kind of job I’m looking for? Ideally, I want something that pays $14-15/hr like my last job as an HR Admin that I was laid off from.
