I do host all my own images at intrepidphotos.com ; you can check the HTML of my posts which embed direct links to high res versions . The problem is that steemitimages caches them (as they don’t trust links will last long enough or be fast enough I guess) and then when you use their interface they display the low res version. Plus no one is asking for high res but 640px is like clip art from 1995 .
