Resolution problems (*aghhhr)

Good morning all, why are you up at this un-earthly hour?

I have a simple query. To simple actually but im scotish so common sense doesnt apply. I have been desinging site with a resolution on 800x500 simply to be viewed in 800x600. I am about to venture into the world of 1027x768. Is there a method that i can use to automatically resize images to fit within a html browser at this resolution (a bit of AS??) if not what is the best defualt to use on this larger resolution without the user having to scroll down a page.

Basics i know, but i would appreciate any light upon this.

Check out my recent site. My first published piece of work. Once again excuse the size (resolution). www.webnetdeals.co.uk
I have only just realised the problems with the about page and the link on the bottom left corner of the main page. I will ammend these ASAP

This was my first real challenge and i would appreciate any feed back upon this

Many thanks

Scott
