I am working on a project in which we are looking to have participants answer survey questions about their reactions to 50 images. We have 300 total images and want each participant to randomly be assigned 50 images to answer questions about. Does anyone know of an easy way to do this? Do we need java? An additional complication is that there are two separate questions blocks that need to be answered by the participant while they view the image (they need to be able to see the image while they answer questions in both blocks). Any help would be appreciated!
