Hello, I am a graduate student in political science. I am new to Qualtrics, so if anyone knows how to make a survey in my mind, please let me know!

So the survey I want to create will be 400 questions, each of which will give 2 pictures for a survey respondent to choose one or the other. All 400 questions will be like that, and I have 400 different photos. How can I make such a set of questions without manually uploading pictures 400 times for all 400 questions? I wonder if there is any way to upload the 400 pictures at once and have each question automatically get assigned with 2 photos in order. Thank you in advance!!!
