It is my understanding that the photo chosen to represent each plant in the database is the one with the most thumbs ups. There are often really interesting photos that certainly deserve recognition but perhaps would not be the best representative photo (e.g., close-up of the bark, a bloom featuring more of a bug than the actual bloom, etc.) . For those lovely shots, I will often give an acorn rather than a thumb to show my appreciation but to not skew the photo into a position to be The Representative. I also often open the plant file itself and peruse the other photos, adding thumbs to those I think are good representatives of the plant and acorns for other cool shots. This gives me a fresh look at the plant as a whole, as often there are many photos I've never looked at.
This is not at all scientific, and I certainly have no problem with the database photo changing up as folks see and like new pictures. In some ways, it would be nice if the representative photo simply rotated through all of the submittals (?). Just a couple random thoughts as I sit here not wanting to get bundled up to go outside in the freezing weather....
