NOT necessary!! I was very fortunate to have pointed out to me:
at which point I clicked on "", downloaded that file, UnZipped
and used MD5.EXE to generate the MD5 values.

So I have a question! If my MD5 values are identical to the corresponding
MD5 values in MD5SUMS, can I assume that I have received three
identical images?

Been there now. Done that! Does anyone on a low speed
connection want a copy? I think my blanks are about $ 0.75
each and the labels plus envelope about the same! Postage
and shipping carton are extra which I can find out.

Sincerely yours,
