Should I use Facebook or Instagram for sharing information?

I not one for the social media craze. But I do like searching the internet for things I'm interested in. I bought this old made in japan (mij) guitar from a friend. It's one of those so called lawsuit guitars. A copy of a 1970's Fender strat. There doesn't seem to be to much info on the internet about this brand name. Not one that most people have heard of. For the past 3 years I have collected about 15 photos of this brand. Mostly from ebay and some guitar forums. I would like to post these photo's and information I have copied to a media site so that it all will be in one location. But I didn't keep a record of where I copied the photos from. And this guitar brand hasn't been in production since about 1982. So my question is "Can I get in trouble for using other peoples photos? If not where should I post the pics and sales flyers I have found about the guitar? I want to do this so that the few of us that own this brand of guitar can one day find out more about it.
Thank You
