This article is from the Fractal FAQ, by Ermel Stepp firstname.lastname@example.org with numerous contributions by others.
A detailed explanation is given in the "alt.binaries.pictures FAQ"
(see "pictures-FAQ"). This is posted to the pictures newsgroups and is
available by ftp: ftp://rtfm.mit.edu/pub/usenet/news.answers/
In brief, there is a series of things you have to do before viewing these
posted images. It will depend a little on the system your working with, but
there is much in common. Some newsreaders have features to automatically
extract and decode images ready to display ("e" in trn) but if you don't you
can use the following manual method:
1. Save/append all posted parts sequentially to one file.
2. Edit this file and delete all text segments except what is between the
BEGIN-CUT and END-CUT portions. This means that BEGIN-CUT and
END-CUT lines will disappear as well. There will be a section to remove
for each file segment as well as the final END-CUT line. What is left in the
file after editing will be bizarre garbage starting with begin 660
imagename.GIF and then about 6000 lines all starting with the letter "M"
followed by a final "end" line. This is called a uuencoded file.
3. You must uudecode the uuencoded file. There should be an appropriate
utility at your site; "uudecode filename" should work under Unix. Ask a
system person or knowledgeable programming type. It will decode the file and
produce another file called imagename.GIF. This is the image file.
4. You must use another utility to view these GIF images. It must be
capable of displaying color graphic images in GIF format. (If you get a JPG
format file, you may have to convert it to a GIF file with yet another
utility.) In the XWindows environment, you may be able to use "xv",
"xview", or "xloadimage" to view GIF files. If you aren't using X, then
you'll either have to find a comparable utility for your system or transfer
your file to some other system. You can use a file transfer utility such
as Kermit to transfer the binary file to an IBM-PC.
