wondering about copyrights.....

[waterlove.livejournal.com]

i've seen a lot of people sell crafts with images cut from magazines, or taken from other places.

aren't there any laws againts this? or is it fine to use because it has no copyright? tons of people use images of betty page, etc on shirts and such.

i know i wouldn't want someone taking a photograph i've made and use it so i just wanted to know.....
