slideshow software?

I need software that can play a number of jpg-pictures in short sequence (0.5 - 2sec), ideally with some cross-fading efx to soften transitions. a slideshow, basically.
the pics will be updated regularly and the software should have no problems with that but just keep looping over that directory...
any ideas?

edit
even better would be I could start up that sw and it would start looping through the directory immediately...

 

seriously?
bummer. that's together with garageband among the first that gets thrown out to make space on my drive...
how to get back?
alternatives?

 

space. no matter how much, it's never enough
i use install templates that are cleaned of all that sw i don't use.

 

thanks! am downloading it right now, dead slow connection though...
hey do i understand right that when installing sw via appstore you don't get a installable image (.dmg, .pkg) anymore?

 

ken burns effect?

wtf? how do i get rid of it? i can't have my pics moving about, it messes up the entire animation (weather sat pics)
2008 iphoto seems to have had the option to switch the thing off
