Randomising Question Choices

Hello,
I am trying to conduct an experiment on somebody's weight affects how they are perceived. I have edited pictures of faces so that I have one chubby version and one skinny version. The participants will be shown an image of the person alongside a quote of what they are saying. The pictures and statements need to be randomised so that each person sees a different combination of faces and quotes. I have created a loop & merge function, with Field 1 as all the chubby faces, Field 2 as all the skinny faces and Field 3 as all the quotes.
My question is: how I can ensure that a participant won't see the two versions of the same face in the loop and merge? Is there a way I can tell qualtrics to show either the face in Field 1 or Field 2? And then a random selection of these alongside the quotes in Field 3?
I hope that makes sense. Any help would be GREATLY appreciated! Thank you!
Emer

    Is there a reason you're using the Loop and Merge function? How many possible variations do you have?
    Personally- If the number of varations was reasonable, would create each unique possible combo as it's own block and use the randomizer in the survey flow:

    Hi Kate - thank you so much for your response!
    Unfortunately I have 72 of each statement and face - so not really able to do it that way. Sadly!

    L&M is designed to ask the same questions repeatedly, so you won't be able to randomize the questions within participants. Therefore, you can either have one participant seeing all the thin questions and the other all the chubby ones.
    However, your requirement isn't that complicated and you could get around that by using an MC question and randomizing the choices. In advanced randomization, you could choose to display 1 from choice 1 & 2 (These would corresponds to your L&M images), while the third could always be shown.
    You may need to play around with the formatting a little bit to get the results looking like a question, but it should be doable.
