Code modification - open to bidding

I used your code for the following experiment: [login to view URL]~himpatel/iat/go/ There are two target concepts: humanoid robot (10 photos) and mechanical robot (10 photos) There are two attributes: warm (5 words) and cold (5 words) Every photo appears once and every word twice in random order. I would like the code to be modified as follows: the words and images should be interleaved (e.g., word, image, word, image...). So the order of the words and images is still random but interleaved.
