Yes.

I don't think it's unreasonable to allow uploading images.  As I said,  
Amazon has limited supported for this.  Unfortunately, most clouds are  
not spending the time to make this work.  I think there is actually an  
opportunity here for someone to create an on-demand conversion  
service.  I would certainly pay for it.
