There are several galleries of Marillion images: latest include dates from the 2016 North America tour.
Prints of the photos are available in agreement with Marillion. Click on the Order Prints and Canvas button to see sizes and pricing. Some photos do not have size options (as they are a non-standard shape), just send a message in the "request a quote" box for pricing. Available sizes are determined by the size of the image and may vary from image to image.
