Docbook, Images, and FOP

[David 'Dox' Shevitz <dshevitz@singlestep.com>]

Hello,

I'm truly sorry if this question has been asked numerous times before, 
but none of my google searches or readings are finding the answer.

I am using FOP to take a docbook document and transform it into a PDF. 
My problem: the images that I am using continually get stretched, 
filling up far more space than they need to and looking just terrible. I 
am taking standard screenshots and using GIMP to save them as JPEGs at 
72 dpi.

I have tried everything I can think of to stop these images from getting 
stretched, but with no luck whatsoever. Is this a limitation of FOP? Or 
is there something I'm not doing? (And yes, I realize this might be more 
appropriate on a FOP user list, but I thought I'd ask here first since 
I'm using Docbook.)

Thanks very much to anyone who can offer some insight.
