I think you need to learn how to use your scanner software's cropping feature.
What's the difference? The thumbnail autoresize is there so that images don't take up an ungodly amount of space in posts anymore. If you don't like the size of the full size image, don't click.
I'm not complaining about the overall image sizes, merely the fact that 60 - 90% of them is useless because he's posted the full image of his scanner's bed for every one - including an end view of a single cartridge. If he'd cropped them closely, they would probably be readable in the thumbnails. If the thumbnails are legible, it's easier to make an informed decision whether one wishes to load the full-sized images.
I wanted to crop the image but my I can't find the crop button on my Atari
