Here is same portrait attaching mode for image gallery with removed names and details with idea to add multiple attachements easily. Basically higlight pictures rounding+add icon for selected and button to add selected.
..edit Maybe bit too crowded, probably one column less..hmm

This just simple merge off full screen and normal mode in nokia maps. In top bar you can see transparent close/minimize buttons but another parts from top are removed. Again pixels used wisely!

.edit
So there is no place to put too much padding or waste pixels on this screen. It might mean not being not so finger friendly, but it´s price what i´m ready to pay to some extent.
