Does anyone know how to get a tooltip or alt text in for the logo?

Instead of using the logo name in the logo box use an image along with %logo. You will have to fiddle a bit with the CSS for positioning and also set the title for the image to what you want the tooltip to be.

Thanks, does that mean I should insert an image tag with title in the logo box, eg: <img src="images/logo.jpg" title="title">.
Where should the %logo fit in?

I was thinking of something like the following in the Configure Header Area box where the %logo is now. You of course have to use the proper atahualpa folder name.

<div id="mylogo"><img class="alignleft" title="title" src="/wp-content/themes/atahualpa353/images/logo.jpg" />%logo</div>

and take out the logo name from the logo box. That should wrap float you logo to the left of the blog title and anything you put for title will show as the tooltip.

Yeah it works! Thanks!!
