>>8782609figurerealm is probably the closest thing and likely has a page for whatever you owned as a child.
I will say though there's a lot of toys not on there and some of their archives are incomplete for pictures.
Your best bet is to google for the toylines you remember and then look them up individually.
I know you're asking if there's like a giant toy archive somewhere, but there really isn't as its a lot to try and catalogue.
