1. what scripting do I use to get this image
http://www.smallcave.net/rock/up/x6syxv800.jpg to appear as the background of a webpage and make it stay in place even if I scroll down, as in my LJ or another HTML document

2. My hd is getting smaller in space as I log online. It would have 1.5 gigs on it but after being online for a while it would shoot down to 1.1, I empty out my internet cache, I run Adaware and Spyware Search and destroy but It just keeps getting smaller. Is there any way I can remedy this?

3. At the risk of sounding dumb. I found this file right smack-dab in my C drive called 'Pagefile.sys' Its about 350 megs and I figure if I delete it I can free up a ton of space but Im afraid that it might crash my XP Pro system, is it afe to delete?
