All,
Just wanted to suggest a fine third party graphic application that
makes it very easy to avoid using bitmap images.
It also enables you to save your screen captures as gifs, jpgs, and
even better, as .png files (portable network graphics) which are
often even smaller and better quality than gifs or jpgs.
In addition, it gives ability to view pictures in almost 400
different formats, and to save pictures in about 50 of those formats
including Adobe Photoshop and Illustrator formats, Amiga IFF (for
any surviving Amigaphiles out there), AutoCAD, AutoDesk, Corel
Photopaint, etc, etc, you get the idea.
And it's free -- XnView is the name of it. A very worthwhile
addition to the toolbox of any list member who wants to post
screenshots without sending the extremely large, HD-Space-consuming
bitmaps.
Best Regards,
Nick Molchanoff
