Ah, thank you, Michael.  By "several" I mean about 6 or 7 files... no big deal. 
In most of the files there is only 1 red rectangle.

One thing I forgot to ask... In another image I have (I attached a screen grab
of part of the PDF), there is a dashed or dotted line in the original JPEG.  I
would like to "recover" the dashed line upon removal of the red rectangle that
was drawn "above" it; that is, upon removing the red rectangle I would like the
result to show the dashed line as if the red rectangle was never added.

How would I do this?  I'm not sure how I would use the technique you suggested
for this case.

Finally, what format do you suggest using other than JPEG?
