So I'm (still, honest!) working on a comedy dio-story featuring the Dream Team I made for the Target Range around Christmas, and I've had an idea for a gag that would involve using pictures for story panels that I would have to acquire online.

Does anyone know what The Rules are for that kind of thing? Bear in mind there's no money to be had from a dio-story, and as things stand I'd probably have to email the story out, but in the event it ever were to be hosted online somewhere would anyone potentially get upset if I'd used things like a location shot, movie still or publicity shot of a celebrity I'd just found on a Google image-search and copied to my HD?

I doubt anyone that could care would ever see something like this anyway but it got me thinking... I always want to know the minutiae of everything...
