Find pictures describing a word

For our mobile game "What's the Word?" we are looking for someone who can find images that describe certain words. In the game, the player is given 4 pictures and has to guess the corresponding word. See the attached files for screenshots of the game. You will be given a list of words, and for each word you will have to find 4 images that together describe the word. For instance, the word may be 'cat', and you would have to find 4 cat-related images. Images have to be royalty-free and free to use (not purchased), 500x500 pixels and in .jpg-format. Good understanding of English is necessary.
