Thunar taking a long screenshot?

[Philip Rhoades]

People,

For browsing my images dirs, I use Thunar with thumbnails - I know I can 
do a simple screenshot that will capture what is actually visible on the 
current screen but is it possible somehow to actually take a _long 
screenshot_ of all the files that are in the dir window? - including 
ones that are off the screen?  I have extensions that can be installed 
in browsers for long web pages that can do this but I would like to be 
able to do the same thing in Thunar . .

Thanks,

Phil.
