 opinion.
 > I think that it actually much better if the image is resized eventhough
 the resized sizes resemble the original size. By resizing WP optimizes
 (compresses) the image and a lot of Plugins hook into that, I defineteyl
 want optimized version for all sizes (images) I render. Maybe we can wrap
 this feature in a apply_filter, so that the user can decide which route to
 go?

 Actually, when the original is optimised, WP creates a larger file, so
 large that even my optimisation plugin can't get it down to the original
 size again, but with a lower visual quality.

 This is a waste of space and processing power in most cases. It's much
 better to either pre-optimise the original file or to let a plugin
 optimise it after it's uploaded.
