OK - remember my resizing script was inspired as a way to help me save time 
putting images up on our (my family's, not the lug's) website.  As a follow on, 
I wrote a bash script to generate slideshow pages quickly & easily.

The process goes like this - get the digital images, resize them and name them 
so they sort appropriately - image01.jpg, image02.jpg, etc., and then place 
them in pwd/Resources, where pwd is a scratch directory.  Run the following, 
and slideshow type pages are quickly generated.

The script is below, and you can see some output by going to http://zuelow.net 
- cringe at the "last updated" date on it, and then click on Phoenie's page and 
see the photos of her birthday.  These are not Pulitzer prize winning photos, 
they're intended for Grandparents and other relatives, all of which are between 
one and three thousand miles away.  But I digress...

Anyway, here's my problem.  As the script runs, it opens xslideshow to view the 
image and then reads a string in for the photo caption in the web page.  But 
when it does this, xslideshow gets the focus and I have to click on the 
terminal window to enter the comment.  I don't want to click, I just want to 
type, press enter, and see the next photo.

Any clues as to how I can get xslideshow to open without taking the focus away 
from my terminal window?

Cheers,

James
