OT: scalling photographs

[Jaco Swart]

This message is Off-Topic, and I apologise for that. But I know that I 
can get fast and meaningful answers on this group, so here goes:

I have a friend who wants to batch-convert scanned photographs from 
hi-res (400KB or larger – wel, maybe med-res) down to e-maileble size 
(aprox 40KB each). He runs Win 98. My first thought was imagemagic, but 
I would rather suggest a GUI solution than using the command line. So my 
question is:

What free Windows program can you recommend to scale photographs down, 
in batches?

thanks
Jaco
