I need some advice on my latest project.

I have an antique radio cabinet that I got at a yard sale.  The radio is
long gone, but I just like the way it looks.  The idea for this project
is to mount a motherboard in the old radio drawer and make this into an
mp3 player that will also display family pictures on a flat panel
monitor.  I plan to make a frame around the monitor and just sit it on
top of the cabinet.  I have a Via ME6000, which is a fan less mini ATX
board with a surface mounted processor running at 600 Mhz. I have a
notebook 40 gig hard drive and a brick power supply.  So the computer is
almost completely silent.

I have loaded Red Hat 9 on this system and its running well.

What I need some help with on is the software that will run the picture
slide show.  My pictures are in several different resolutions and I
would like to have something that will auto size them so that they all
fit on a full screen.  I have tried GQview and a few others, but so far,
I have not found anything that will do a full screen slide show and will
auto size the images.  Does anyone know program that will do what I
want?

Thanks

Devin
