export the image as a jpg. Make a thin slice, set jpg settings, use preview to see it. export
In Dreamweaver apply to footer as a CSS background, repeat. if need help with css just ask
Sorry for so short a description, hand in cast :-)
You will get this sometimes, even with jpegs in FW, because FW doesn't dither the gradient. You might have better luck with a PNG 24, sliced thin as Joyce suggested
You can also try adding a tiny bit of noise. Add a rectangle above everything else, add noise to it (look under the Filter menu, I think), then play with opacity and blending modes till you get just a little bit of randomness to your image.
Thanks for that, didn't think about using a slice and then using as a CCS background and repeating.
That wouldn't work on what I was doing originally as I wanted the highlight to be curved, to give a spotlight type highlight.
I have done this loads of times on other sites but with colour and never had this problem.
Anyway, I use repeating slices all the time for page backgrounds etc so no prob there.
Clearly what I want isn't working with black and grays and have tried everything form jpeg to png24 so will do as a slice like you suggest and just live with the fact it isn't quite what I wanted.
Thanks guys ;-)
