WebBMP - A simple
plug-in I wrote to view BMP image files; includes source
list your installed plug-ins and MIME types.
[View as text - in case Netscape won't show
you the source code]
Doesn't work on all browsers, such as MSIE. Also, try Help|About
Plug-ins then View|Page Source.
From Netscape's knowledge base
How do you enable a plug-in when you have two or more that handle the same file type?
