Gonna open a can of worms here

[ladypeacem.livejournal.com]

I'm really wanting to sell some of my collage projects on ebay and am looking for advice. I make collage/decoupage projects from magazine photos and thumbnails of arts and photographs. Does anyone know the legal ramifications of selling stuff like this? I have heard both extremes of the issue but wanted other opinions.

BTW here's a shameless plug. My website http://www.alternativelives.org is back up and I'm setting aside space for a online market place. Let me know if you are interested.
