INSTALLATION NOTES
If you associate a file extension with WinJPEG, you can double click on
a file with that extension in File Manager and WinJPEG will
automatically display that file.  There are two ways to associate an
extension with WinJPEG.  The easiest way is to run File Manager, to
click on a file with the desired extension, and to select the Associate
command from the File Menu.  Then type "winjpeg.exe" with the
appropriate path (e.g. c:\winjpeg\winjpeg.exe).  The other way is to
modify the Extensions section of the "win.ini" file in your Windows
directory.  Your "win.ini" may look like this after you modify it:

[Extensions]
...
jpg=c:\winjpeg\winjpeg.exe ^.jpg
gif=c:\winjpeg\winjpeg.exe ^.gif
tga=c:\winjpeg\winjpeg.exe ^.tga
bmp=c:\winjpeg\winjpeg.exe ^.bmp
pcx=c:\winjpeg\winjpeg.exe ^.pcx
tif=c:\winjpeg\winjpeg.exe ^.tif

Note that you don't have to use the suggested extensions (e.g. you can use
.jpe instead of .jpg); WinJPEG will automatically detect the file format.

If you are using Windows 3.0, you must copy "commdlg.dll" and
"shell.dll" to your Windows system directory(e.g. C:\WINDOWS\SYSTEM).

If WinJPEG GPF's, we recommend that you restart Windows before
running WinJPEG again.


HOW TO REGISTER
If you use WinJPEG for more than 14 days, you are expected to register
WinJPEG.  When you register, you will receive the latest 286 and 386
versions of WinJPEG, a user manual, and a collection of JPEG images (we
will put as many as we can fit on 2 720k 3 1/2" floppies, on 1 1.44M 
3 1/2" floppy, or on 4 360k 5 1/4" floppies).  Also, the registered
version does not have the reminder-to-register screen at the start.

The registration fee is only $20.  MA residents, add 5% sales tax to the
registration fee.  US residents, add $4 for shipping and handling;
non-US residents, add $8 for shipping and handling.  If you want
WinJPEG e-mailed to your account instead of having it physically mailed
to you, there is no extra shipping charge.  

Registered users of WinJPEG can purchase the latest version for $5. 
Shipping fees described above apply to these updates as well.  Updates
are available when you see a new shareware version.

For e-mail registrations, you need to use a program called "uudecode" to
decode the uuencoded file that we e-mail to you.  For your information,
a uuencoded file is a binary file that is converted to text by a program
called "uuencode".  If your mail system rejects large messages, we will
split the uuencoded file into smaller parts before mailing the parts to
you, and you will need to edit the messages with a text editor before
you can decode them.  Compuserve, for example, does not permit large
e-mail messages.  Also, the uuencoded file is rather large; it is
greater than 500k for WinJPEG.  Compuserve users may find it less
expensive to receive WinJPEG via U.S. Mail.

Registrations with the incorrect fee or with non-US currency will be
returned.  Foreign registrations must send US currency or a check drawn
from a US bank.

To register, complete the order form and send a check to:

      58 Chandler St.
      Boston, MA 02116
