I have 500 images. I want responders to be randomly assigned 10 and rate them 1-5. 

From what I’ve understood, the best way to do this is to create multi-choice questions for all and add the images to them - and use the randomizer for the random assignment.

The problem here is that I would have to create 500 questions and add the images to them one-by-one. 

Is there any other way to do this that does not require me to add everything one-by-one? (Is there another way to do the randomization not requiring the creation of all the questions to be chosen from or is there another way to do a “bulk upload” - perhaps by writing some code that creates a file (e.g. csv) detailing the form that I can upload online)

Update: I am preferably looking for a solution that works with a free account, but I believe I will be able to get a premium account, meaning that any solution using the API would also be appreciated :)

Thank you!
