Just my two cents on multiple pictures...
When I submit a photo of a plant, I don't always consider the picture I'm submitting to be better than ones already submitted, but I submit it so that there's one in the database that represents my area. When looking at photos of plants in the base that I'm comsidering buying, I don't look for the best looking photo, but the one that is from an area closest to my own in growing conditions.
WHen it comes to some plants like sempervivum, I'm submitting multiple pictures - from different times of the year. Some will look very different, and some will look the same, but some semp collectors will appreciate the information on how individual varieties change (or don't change) throughout the year.
