I have a situation where I'd like to stick to using my logo instead of the actual text for my h1 tags. if I put in my keywords in the alt tag, instead of actually written, will I suffer in SEO. Is it better to have both text and an image? Thoughts?
<div id="hdr-top-logo">
<h1>
<a href="/">
<img src="logo.jpg" alt="keywords and title" />
</a>
</h1>
</div>
