I'm told that I can replace the colorful windows logo that appears as
windows invokes with a graphic of my choosing.  The challange is that the
image must be in 'RLE' format.  I've got GIF's, PIC's, JPG's, TIF's, etc...
everything but RLE's!

What's the best route to converting these things?  
What program should I download, and from where?  
Has anybody else done this, and do you have the steps available?
