Thanks for your insight bannedinbc and kafralal!
I think my biggest issue is that I have 6-7 separate series of several images each, so in order to show all of the images in my portfolio I would need to upload almost 55 individual images. Since each school allows only a maximum of 20 images, I have to choose between uploading only 2-3 images from each series or figuring out some way to show all the images from the series in one frame and then uploading individual images as details.
I think the person who told me I should print and install them, said so for the purpose of showing the totality of each series in one image.
I'm wondering if anyone else has experienced this issue and how they resolved it for the application process?
