Powerpoint likes 800x600 for horiz images.
Trouble with pure images, meaning not in a presentation program, is that your
screen rez and
projector rez will come into play. (your images are 1024 and projector only
does 800, etc, where
as PowerPoint will scale the presentation to match your screen resolution).
All that being said, it's a rare projector that won't do 800x600 anymore. Then
again, if your puter
is running only 800x600, you will need to show them in Irfanview slide show
mode (as opposed to
just viewing each image in the main program itself), as just the menus will eat
up some room and
image would have to scroll to see it all.
And you don't want Irfanview to scale your images to fit window, quality
suffers.
Guess my final advice is to use PowerPoint :-)
If not, then 800 x 600 should do it, one way or the other, but you really
*should* make sure you're
not getting an antique 640x480 projector.
