Your background layer should have the color you want to be transparent. For example: Fill your background with white. Then place your objects on new layers. When you

In the Save for Web dialog, make sure gif is chosen and Transparency is checked. Select the eyedropper over to the top left. Click with it on a color in the image window of your choice and then click the little transparency icon at the bottom of the Color Table box.

However I think you are better off making your graphic transparent to begin with and then using Save for Web.

Just click all the colors in the color table that you want to be transparent while pressing the shift key. Then click the transparency icon underneath the color table. Is that really so complicated?

As I suspected from reading online help page (after page), but hard to believe

I understand the advantage of matting to blend more smoothly to the page color, but if the webpage colors change then the entire image has to be re-edited????? I have deja vu of retro cludges of writing the html background to match image canvas color for jpgs……..

This does not sound like an improved procedure at all, to me.

I am not criticizing your help, Clinical. I am speaking of Abode’s feature implementation. This would also mean that there is only one color that can be set as transparent, yes? Export to GIF89A was a 2 click process AND you coud add colors to the transparency map by holding shift while continuing to click using the eye-dropper. Who the hell beta tests Adobe PS pre-release versions, anyway? LOL Thanks for the explanation, which probably is embedded in a series of help pages. But, I think I will just install the Export as GIF89A plug-in, if it is in fact usable with 7.01.

For web work I continue to think Ulead or Corel have always been ahead of Adobe and much more intuitive. For pre-press, PS has always been my preference.

Thanks for the explanation

You are criticizing Adobe for having a feature other programs don’t have. If you don’t want to set a matte color choose None.

Thanks. That explains it succinctly. The online help file never made it so clear.
