Steempeak at least lets you change the feed view to make the photos bigger. If you click a picture in a post it zooms it up and you can cycle through the others with the arrow keys. That is neat. Photographers will demand this sort of feature. I really think Steempeak is what Steemit could have been and it's my main UI on the PC.
I haven't really given Steempeak a go yet. I really like the clean look of Busy the most, so I spend most of my time on that.
You should give it a try. They seem to have had photographers in mind. It uses Steem Keychain to log in.
