I was thinking...uh oh...dangerous!
What do you think about having a permanent spot in the Recent Images section for each of the "Biggie" genera?
Rose, Daylily, Lily and Iris come to mind (sure I am missing some).
That way one of those would always be displayed on the homepage to entice new people to the site, as those are the major genera 'players', so to speak, that alot of folks have interest in.
Just a thought.
