I know how to run a batch resize based on fixed width, height, or percentage... but what if I have a number of photos of all different sizes and shapes and I want them to be roughly the same size visually? I am using photoshop, but could try fireworks or some other thing, but hopefully nothing too complex.
I guess this would mean the same number of pixels in each image (as in the example image), but there may be a better ways of determining.
Max-height and max-width constraints on a percentage resize would probably suffice here as well.
