Maybe the designers can help?

When I was participating the contest, I got in my feedback that I could not use coloringbook-images, like the parrot in my "Tropical Wishes".

But, what if I see a greeting card with a drawing of a parrot on it. I buy it, scan and extract it, is this allright?

Another thing: I buy a doll, take a photo and extract the doll to use in a kit.
Is that okay?

What if it is a Barbiedoll? LOL!
My daughter and I loved to make clothes for them, could I take a photo and extract the doll, or is this not-done?
