Irrelevant. The camera might have been fantastic but that's nothing to do
with blowing it up and still looking sharp in this instance. He's not
blowing up the original photo, he's blowing up a scanned copy of the
original. Unless the photo was scanned at some extremely high rez and posted
it in some lossless format, the original observation doesn't make sense.

Not entirely correct. The original must have been sharp enough to
display sufficient detail before the original scan.
If the photo was a jpg, it would show significant artifacting blown up to
10x -- I doubt anything would even be recognizable. And I doubt it was a
lossless format such as BMP or TIFF as the online file size would have been
ginormous to hold that much information, assuming a scanner anywhere could
have scanned that much info in.

I agree with your comments about JPEG but it could have been in PNG
format which is a compressed, lossless format that resembles GIF but
allows more colours. Since the picture is B/W the number of colours is
really immaterial except for the amount of shading which can be
applied. It is highly probable that as a B/W image it was in GIF
format. This would allow for expansion up to the original size with
little need for interpolation.
Either:
1. The original poster might have been exxagerating somewhat. (My guess. . .
:) )
2. PSP has some amazing internal algorithm for interpolating zoomed in
images.

I have to agree with this. It's unfortunate that PSP is off-topic in
this group.

When a picture is blown up, it becomes blurry,
Is there any freeware, shareware or others
programs that will enhance the resulting image?

Of course there are, but I don't know many.
Today they enlarge 35 mm photos as big as big houses -
to cover construction sites with advertising etc..

A freeware that can improve your pictures a bit is
QE Super Resolution. Built to extract still pictures from videos it can
very well enlarge jpg, jpeg or bmp to the size you wish, adding similar
pixels into the 'neighborhood' of the existing ...
