custom images

Have themes that could generate images for links so that navigation doesn't have to be plain text, or be able to generate an image for the title of a site or page so its easy to change the title of the site and still have it look fancy.

This could also include being able to customize the image such as by:

• adding an icon - this could apply to a specific navigation item
• setting the text color or font - this could apply to a specific item or be applied to all relevant items such as all page titles or all navigation links
