i have a website where firms can have a page dedicated to them ( like a directory ) and the sellers of my website are responsible for taking photos of what in the firm the administration of the firm wants to have on their page.
now the problem is, i know the images aren't copyrighted and if someone wants to screw me and make my website take out thousands of images and make my sellers go to all firms to re-take photos causing a massive prejudice i think they would simply copyright them all and communicate with me to take out the images or sew me.
how can i stop worrying over this, i don't want to be copyrighting images from my clients almost every day in order to be 'protected'. i think i'm maybe concerning more that i should or that this stuff i said has to have a flaw or some corner-case anywhere on it.
any good suggestions?
