More troublesome, for me, is uploading time. My internet connection is not so great, it takes me ~5 minutes to upload this 12MB file. A 60MB file would take 25 minutes... and although it's less than half an hour, it's too long for uploading a book, I believe.
The other reason is more "aesthetic". I think it's a waste of resources to use 60MB for something that should take only 12MB, it just doesn't look right.
But, as I said, I'm not blaming anything on you. Mobiperl is already a great tool!
I am still thinking in terms of 64kb maximum image size... As I undertstood it it was only one image that was duplicated so I do not get how you loose more than the size of one image per book.
"aesthetic" is a good reason. Against that is the risk to introduce bugs when you have to have more complex code.
