Various pictures for the same question for different HITs

[Sadegh Moosavi]

I need to post a servery of about 50 varied questions. Each question needs an image. This image should be selected from a set of images, so each workers sees a different image for that question. How can I manage this in the code? For example, I have 50 different questions to ask 60 workers. I have also 50 (number of questions) sets of images each containing 60 (number of workers) images, so each worker sees a different image for each question. I am completely new to MTurk. I will be thankful if I get help in any way.
