part of which runs:

"Open the paint tools in RR and use the eraser to click each image, 
then, immediately click undo: this converts all images into internal 
bitmap format. However this means that the files grow to about twice 
their original size."

So . . .  presumably if that still goes on the way to check is:

find out an imported image's size,

do the 'thing' with the eraser,

find out the imported image's size again:

if it has doubled then it is probably now RLE.

However; the conversion to RLE format was NOT automatic, and only 
necessary for display on Macintosh systems; presumably Os 9, 10.1, 10.2 
and 10.3.

At the moment imported images seem to display on Mac OS systems (10.5, 
10.5, 10.7, et al)
without any eveidence of internal conversion.
