@kueda yes, thumbnails are thumbnails, but these thumbnails have lots of things on top of the them which reduces further the visible area. On each picture is an avatar, number of photos icon and a reviewed overlay; and on the taxon name is the Agree button. All these things are useful and super and appreciated, but they do reduce the readability and image area, and one has to be careful where one clicks! I also think the leaderboard is not useful to ID’ing stuff and could perhaps be on a separate tab like on the Explore page.
In fact, moving the leaderboard to a different tab might reduce the number of people who agree compulsively just to get up the leaderboard. {I strongly believe that identifications and agreements should be separate things anyway, but that’s a different topic.}
