I have a vertical bar on the left on the index page. How ever I move the width markers it either disappears and makes the page left oriented or I have to live with it. Any suggestions?

I have been recommended to reduce the size of the images ( from say 350k to 100k) but it made them quite blurred. I have now restored most of them. Any hints on how to speed up the pages?
