I don't really know much about gifs, but I read somewhere that there is certain rules or copyrights on using them?
Can anyone tell me the scoop, or at least point me to where this info is located?  Thanks a bunch......

here is a little story in english
In 1987, CompuServe designed the Graphics Interchange Format (GIF)
specification for graphics files. The GIF specification incorporated
the Lempel Zev Welch (LZW) compression technology on which Unisys
Corporation was independently pursuing a patent filing. In early
1993, Unisys notified CompuServe of patent rights granted to LZW. At
that time, CompuServe began negotiating with Unisys to secure a
licensing agreement. This agreement was reached in mid-1994, and
CompuServe then initiated a process to secure a similar license that
would benefit its GIF developer community.

Following the agreement reached between CompuServe and Unisys,
CompuServe announced the Graphics Interchange Format (GIF) Developer
Agreement, shortly after its completion, on December 29, 1994. This
agreement is aimed at GIF developers who are developing programs and
shareware primarily for use in conjunction with CompuServe. The
service offers a license to these developers to use LZW technology in
programs written to the GIF specification.
CompuServe remains committed to keeping open the GIF 89a
specification both within CompuServe and in areas outside CompuServe.
CompuServe continues to strongly support the use of the GIF
specification in the entire online community including the Internet
and World Wide Web. This agreement will be transparent to end-users
and will not result in any charges for people using viewers or
transmitting GIF images.

The agreement offers software and shareware developers who use the
LZW technology in their GIF programs protection under a software
license that CompuServe is authorized to grant under the agreement
with Unisys. Developers who choose to take advantage of this service
would acquire the rights to use the LZW technology in certain
software and shareware developed primarily for use in conjunction
with CompuServe. Developers who choose to participate in this
agreement within the implementation period will also benefit in that
Unisys has agreed not to pursue royalty claims for past use of the
LZW technology in GIF. The implementation period has been extended to
January 31, 1995.

CompuServe has presented this new agreement as a service to its GIF
developer community. Cost to developers will be a $1.00 one-time
licensing fee and a royalty payment of 1.5 percent or $0.15,
whichever is greater, per registered copy of a program containing the
LZW technology. CompuServe will not profit from this service.

CompuServe encourages developers to work with Unisys directly if the
GIF Developer Agreement does not meet their needs. Unisys is
continuing to make the LZW technology available to any interested
parties under reasonable and non-discriminatory terms. Developers
are not required to register with CompuServe. Registering with
CompuServe is simply one option for addressing the Unisys LZW patent
issue. Developers may want to consider consulting with legal
counsel.

CompuServe is committed to keeping the GIF 89A specification as an
open, fully-supported, non-proprietary specification for the entire
online community including the World Wide Web. Whether they choose
to register with CompuServe or not, developers are encouraged to
continue use the GIF specification within their products.

A copy of the GIF Developer Agreement is available in the Library
section of the CompuServe Graphics Support Forum (GO GRAPHSUP) and
will shortly be posted to CompuServes World Wide Web page
(HTTP:\\WWW.COMPUSERVE.COM). Developers who are not developing
software primarily for use in conjunction with CompuServe should
contact Unisys directly at: Welch Patent Desk, Unisys Corp., P.O.
Box 500, Bluebell, PA 19424 Mailcode C SW 19.

I know vb and Delphi, but I am not really interested in VB anymore. :)  So I guess it is Delphi only :)
