background with multiple composed images

[luca marletta]

Hi list,
I'm wondering if there is a easy way to manage several images that I
use as optional background in my site as one, in html template.
I mean, I have a background done composing several maps, each is a
separate image. Which way can I select all them in html template just
in one select managing them as one big images?

Maybe is a easy question but I'm new in mapserver.

thanks a lot

luca
