Finding picturable words

I want 200 pictures in the public domain that are at least 128x128 pixels. These pictures will not be proper nouns. I want at least 100 nouns and at least 50 verbs. The files will be placed in a drop box and the file name will be what the picture is - for example a picture of a dog will have dog as the filename. These words are meant for early learners (4-7 yrs of age) so words like "concussion" with detailed drawings of a brain's anatomy post-trauma will be immediately rejected. "Dog" is a good one. So is "cat". A good verb might be "eat". An adjective might be "red". Please keep the child aspect in mind. Any pictures of an object should have the surrounding area cropped. So a picture of an airplane will not show the sky, just the airplane itself. Drawings are acceptable as it doesn't have to be all photographs.
