I disagree with you on this point, it is easy to test this.

If it is just eye candy, it is not html content, call it as a 
background image from the stylesheet rules.
A stylesheet background  image has no alt text but it is also invisible 
with CSS turned off.
Isn't this what stylesheets are for formatting eye candy.

I have seven different stylesheet options each with different heading 
eye candy animated gif files.
If I embedded these images in the page html, they might think they are 
missing something.
Put eye candy in the stylesheets not in the html code.
