create mockup of stairwell with movable shapes scaled to represent frames I aim to hang in my stairwell.

I want to hang a group of photos in my stairwell. Beforehand, I want to play around with different layouts to try to visualize what would be the best way to group them in the stairwell. I need something on a program that allows me to move these shapes representing my photos (scaled to represent their sizes as listed below) on my three stairwell walls (called to represent its true size as shown on attachments) . Doesn't have to be exact, but close enough to be of help. I'm trying to figure out how to hang some photos in my stairway. I need a scaled mockup of my stairwell similar to what I will attach, but which allows me to move the photos so I can try different looks. The photos which I'd like to be able to move should be scaled to the following dimensions and layouts: 5 portrait photos of 20” x 30” 3 landscape photos of 30” x 20” 2 portrait photos of 24” x 36” 3 landscape photos 36” x 24” 2 landscape photos of 40” x 26.66” 1 portrait photo of 26.66” x 40” 2 portrait photos of 30” x 45” 1 portrait photo of 27” x 36” 3 portrait photos of 20” x 30” 1 portrait photo of 24” x 36” 1 portrait photo of 24” x 30” 1 portrait photo of 19.5” x 26” 1 portrait photo of 22” x 29” 2 landscape photos of 25” x 20.5” 2 landscape photos of 36” x 24” 1 portrait photo of 26.5” x 40” 1 landscape photo of 48” x 32”
