#container {position:relative;}
#container #feedarea {position:absolute; padding:0; right:25px;}
#container #headerimage {display:none;}
#container #header {height:181px; width:950px; margin:50px 25px;}
#container #header h1 {display:block; margin:0;}
#container #header a {display:block; text-indent:-999em; background-image:url("http://shonshon8.files.wordpress.com/2009/12/leopard-print-bkgd-red_950pixels.jpg"); height:181px; width:950px;}

<div align="center" style="width:100%;top:73px;left:0;position:absolute;z-index:11;">
<a href="YOUR BLOG URL HERE">
<div style="width:760px;height:190px;">
</div></a>
</div>

But you've changed the dimensions, so you'll have to change the numbers. The width and height of the inside div should be those of your header image; if you can't calculate the proper top and left numbers for the outside div, try this first (a red rectangle):

<div align="center" style="width:100%;top:73px;left:0;position:absolute;z-index:11;">
<a href="YOUR BLOG URL HERE">
<div style="background-color:#f00;width:760px;height:190px;">
</div></a>
</div>

Adjust the numbers till it falls in place, then delete the bg color.

Thesacredpath or hallluke will probably be able to give you the CSS-upgrade variant of this solution or suggest an alternative one.

That is why I can't give you any help on this. I'm not going to waste my limited bandwidth allowance.

To turn comments off site-wide (for any new posts or pages) you go to settings > discussion, disallow the comments and then save.

For any pages or posts that have already been published (before the change at settings > discussion) you have to do it manually in the editor for each page or post.

The blog I am referring to is http://mimiderose.wordpress.com. I deleted all of my pages and re-created them but the comments option was still beneath the editor. Comments and revisions are all I see. No where do I see the option to remove or not accept comments. I registered for a Premium account so that should not be the problem.

This is what I see on the bottom of these pages:
Posted in Uncategorized | Comments Off

I see no "pages" on your blog.

If you do as I said above, the comments off thing will go away everywhere, and the categories and tags below the posts on the main page as well as the single-post pages will go away also.

But that will also remove the categories in Mistylook since the category list and the "comments" text are both controlled from .postmetadata .

Joy and peace,

Best wishes for a happy ending. I'm sorry I was unable to help you.
