Sannyasin,

Actually it was your introduction of the  image size property that 
gave me the idea. Being an old FORTRAN programer, I never made 
effective use of this ability in RR, always making do with the 
construction of global variables to do the job. But a property is a 
global variable without all the overhead (declaring it global 
everywhere you use it.)

So if you use your resizeImage handler and reference the *fixed* 
image size *property* rather than the current image size in the 
substack you needn't worry about past actions on the image.
