program for viewing multiple folders

[waigy]

Hey Man

Can you guys recommend a program that lets you view jpegs that are inside loads of different folders as one slideshow.
I've gave a copy of all my jpegs from a 1 year trip in Portugal to a mate.
They are in loads of different folders usually named as the date the pics were taken.
Some folders only have a few pics in, others have hundreds, but currently he has to open each folder individually then view them in a slideshow program.
It takes ages to view them.
Any suggestions?

Cheers Man
