Image instead of title
 

Is there a way to get a image to display instead of the product title text on a single product page?

You could, but it would not be a good move for SEO. You could do something with the productid - like:

<img src="{$ImagesDir}/{$product.product}.jpg" alt="{$product.product} />

That would link an image called productid.jpg (replace productid with the actual id)
