I just came from the Sempervivum entry and playing with the Random photo feature. Most of the photos that come up are great, but there are the occasional ones that are not very appealing to have showing in the Random feature. I just had one refresh come up with three different not so appealing photos all at one.
I am thinking it would have more visual appeal if only a moderator chosen photo was showing. The moderator could take into consideration what the viewers in the entries are finding the most appealing. In entries where there are none that would be suitable it just wouldn't be enable to show in the Random photo feature.
Would this tie in with what Rick is saying above?
