I use the FIR image replacement method in the Nav for www.message.uk.com
I liked the fact that it gave me more control over how the nav
displayed in standards complaint browsers, however in older browsers
and user agents that don't support the advanced css, they just get a
list of links.
The only problem is that if people come to the site with images off,
the nav is unusable. Not many people surf with images off but some do.
Either because they are on crappy connections or because they have to
pay for their bandwidth downloads. However it still is a problem.
I wanted to use the FIR method on the blog I'm building
(www.andybudd.com/blog/), however have decided to stick with images
because of the above reasons. However it means that it'll be more
complicated to do things like style switching if the images are
embedded in the page rather than brought in externally in a style sheet.
That's the real power of the FIR method and it's derivatives. It's not
a question of why you would want to swap an image for text. It's about
allowing you to swap images with other images in the CSS while still
keeping the meaning and integrity of the original document.
