I am presently testing the first version of SDB to support storage 
and retrieval of binary data [in this case a signature created using 
Rev's pencil tool].  I store and reset ONLY the TEXT property of the 
signature image.  I've now repeated this dozens of times with no 
problems.

Rev Dictionary notes that using the imageData of an image displayed 
at less-than-full size as the source of another image causes a loss 
of image detail.  Even at full size, I presume the imageData shows 
the image at 72 dpi of my screen, not the 250 dpi resolution of the 
image's TEXT.  If so, simply storing the imageData somewhere and 
using it in a new image (or in resetting the existing image) causes a 
loss of image detail.
