Re: Dynamic image as table background

If you use CSS you will have to supply the path of the image under the
webserver (I think - better minds than mine can correct this). So, if it is
not too much hassle, you should stream the image out to disk. If you only
have a few images, maybe this is no big deal. Especially if the churn rate
on them is low.

Or maybe there's a way to use a WOImage in a hidden div and reference that
as your table background? You will need some javascript for this, I guess.

Again, just thinking out loud here...
