There are tools to compress images. Many free hosts used those in the past to make pictures smaller. Good part in this case: it distorts the pictures... So if you'd compress all images to 99.9% of their original size (which wouldn't affect the image quality, but would totally alter the code in the picture) any program trying to use the data in those pictures wouldn't work anymore.
Try making a JPEG in PhotoShop. Save it. Then save it again setting the quality of the image 1% less. Try to find ANY difference in the results picturewise. You will not find it. But compare the two files in a text-editor. Totally different.
It would take some extra processing power on the upload script, but this pretty much takes care of all these warez programs combining JPEGS to full files
