This article is from the sci.fractals FAQ, by Michael C. Taylor and Jean-Pierre Louvet 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:
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 you are
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 or JPEG 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.
Most of the news readers for Windows or Macintosh, as well as web
browsers such as Netscape or MSIE will automate the decoding for you.
This may not be true of all web browsers.
