After setting a price list it would be useful if the displayed price of an individual image could be automatically filtered based on the image aspect ratio.
For example, the price list would contain all available print sizes offered by the photographer regardless of aspect ratio (8×12, 16×24, 12×12 etc) and then when adding images, the aspect ratio of an image is calculated. When the add to cart function is called, the available print sizes would then be filtered by the image aspect ratio to display only the available print sizes for that particular image. Square crops would only show 12×12, 16×16, whereas a 3:2 crop would show 12×8, 24×16 for example. This would allow for the use of multiple crop ratios within galleries.
