Ok Got a couple of stupid questions for you Pure CSS gurus.

1. I am refitting my site to be pure css but i find when i am going in and doing this i usually have at least one image on the page that just visually communicates the theme or idea of the page. That being said
should i just leave the image tag out there in the flow of the document?
should i put it in a div to make it easier to work with in the future?

2. I would also like to know what do you guys do with Forms?? Do you still format them with Tables to make them line up right? Or is thier a better way to do this with CSS?? Any Linksto tutorials on this subject would be greatly appreciated.

I know these seem like a stupid questions but i figured get some ideas what others do and it may give me some ideas for my refit.
