Created a "justified" layout for the photos on the photoset
pages...
Allowing a bit more width for the content of the site...
Dealing with the last row of images - making sure that they are the
same sort of height as the ones which have been justified to pages...
Finessing the layout to make sure everything lines up properly and
the super wide photos never push anything to the next layer...
Making sure the image we select is good enough quality to display
on the list page (especially necessary for panoramas)
