Hi, adding pics legally

Hi, I can't find anything on the forum regarding this, although I'm sure there is something there....how do I legally use pics for my articles? Do I just use free stock pics? I received a correction saying that some of my pics were from allposters, but I didn't use the allposter module? Could someone help me please? Is it ok to use any pics as long as you put a credit there?
Thanks.

Here are a couple of Wizzley pages that might help you.

If I use my own photos I add them alongside the text in a text module. I also use the Zazzle module to add pictures from there.

The Wizzley Help Page has info too about the individual modules. Hope this will help you out.
