Sorry, no option to show randomly. The homepage feature only shows new media. It can only be toggled to show or not show at all. I do think it adds something to have them. I just wish they turned through a bit faster.
Well, I was wrong. I didn't see it when I looked. After a bit more investigation, I found it. Thanks for the suggestion and follow up! It now shows random media.
This Random is Great! Let's us all see everybodys works and ideas. If you want to see an album from any randoms just click on a pic. Brings you right strait to that users Albums. Thanks greatly to Grassius Crassius, Erics and motorbicycling.com.
