My sister-in-law is getting married this weekend and I've been instructed to scan a few hundred photos for a slideshow that will play throughout the reception. I've completed the scanning and cropping but am now having trouble with what I assumed would be the simplest task....finding a suitable slideshow program. I have a folder with about 400 pictures that are named pic001, pic002, pic003, etc. I've basically scanned in all of the bride's pictures first, from her kid pictures up through her college graduation and present day, then scanned in the groom's kid pictures up through his college graduation and present day. Needless to say, I want the pictures to be completely randomized throughout the slideshow, not show all the bride's pictures first and then the groom's, only to repeat. I didn't figure this would be a big deal, but thus far I've tested Windows Live Photo Gallery 2011, Picasa 3.8, and Zune, and none of them seem to offer a random option with the slideshow. This completely baffles me. A google search shows that Picasa doesn't even have the option, Zune doesn't have the option, and I can't find any info regarding WLPG (but the random option isn't there, I've looked everywhere). The only slideshow option I can find is with the Windows 7 photo viewer, but the problem is two-fold. First, I'll be using a laptop with XP, and second, I want a slideshow program with some kind of pan/zoom, fading effect...not just a static switch from picture to picture. Can anyone recommend a program (preferably free) that can manage to do a random slideshow with at least some minor transition effects? EDIT: As soon as I posted this thread, I remembered using Irfanview a few years ago for batch processing. I just downloaded it and it allows me to do a randomized looping slideshow with very simple fade transition effects. I wouldn't mind for a little more fancy transition effects, so I'm still open for suggestions. However, Irfanview will suit my needs should I not find something better.
