RIM's dumb asses killed this option with one of there many OS updates it don't work no more. Used to be 4 n 6. Would be nice to still have this. You can veiw slideshow and it will cycle through your picks. Then you can hit options and go next and previous or pause on a pic.
Just fingered this out too. I was settin a primiscuous pick for my desktop(er however Ya spell it)and noticed if your viewing a pick you can hit options and then click next or previous. Not a shortcut but better then hitting back and clicking another pic and waiting forever for it to load again.
