Computer Graphics with Photoshop - Saving (part of) the color table

Saving (part of) the color table

Here's a scenario that I find myself in occasionally.

Today I created a simple graphic logo for a company's website. If I
save it as a GIF with a color table of 16 colors, it looks perfect.
But now I've got to incorporate a small photograph with it. Saving it
as a JPEG will make the logo part look fuzzy. So I increase the size
of the color table to include (at least some of) the colors in the
photo.

But the new larger color table has NOT included all of the colors
necessary to give me my good-looking logo. It has included a few, but
most of the colors have been re-assigned to colors within the photo.

I'd like to somehow save the color table that is created without the
photo, then save the result as a GIF using a much larger color table,
but keeping the colors that were in the original.

I've probably done an abysmal job explaining this, but if anyone can
help.

BTW - I'm using 5.5 on MS Windows.

Short of saving them in a more suitable format such as TIFF, you may need to
save them separately and then superimpose them on the web page with HTML.
Save the logo as a 16 color GIF and the photo as a JPEG.

Maybe a master palette can do what you want (not sure though).
Master palettes can contain colors from different images and can
also be saved as optimization options to be used in ImageReady's
Optimize palette (or from Save for web inside Photoshop).

Try F1 in ImageReady and search for the word Master Palettes.

I would have done something like that, but the logo has a drop shadow
that fades into the photo. I think I'll just save it as a 256-color
gif. It'll have to be good enough.

Thanks for the suggestions.
