Judy,

Thanks for all your efforts to support The Movement.  :-)

I can't answer the question you are asking, however, I use a perl script 
that invokes ImageMagick to add watermarks to large quantities of images.

http://www.imagemagick.org

Since I do put my watermark in the upper left corner, I have not paid 
attention to whether ImageMagick can apply the watermark based on the 
position from the lower right corner, but I would guess that it can.

And if the answer to that is no, there is another trick you could try, 
especially if you are using a script to batch process.  First, make your 
watermark image upside down and backwards.  Then rotate each image 180 
degrees, apply the watermark, flatten the image, and rotate it back to 
upright.

Last note: When I batch process to apply watermarks, I always only apply 
to _copies_ of the images as invariably I later need the original 
without watermark for some other use.  (This also prevents destroying 
the original if your batch script does not do as expected.)
