Bootskin: How do I keep same palette with PS?

I created a Bootskin and would like a progress bar, but everytime I try to get the two images to have the same 16color palette, it never works. How do I use the same palette between two images?

First covert your image into 16 colors:
- image menu -> mode -> indexed colors
- Local (selective), colors: 16

Then save the color table:
- image menu -> Mode -> Color Table
- Click save

Then in your progress bar image, load the color table:
- image menu -> Mode -> Color Table
- Click Load

That's it.

I'm using PS7

I can easily reduce it to only 16 colors, but when I go to save the BMP I can't select anything less than 8bit. Thus, when I load the bootscreen, I just see the old windows bootscreen in funky colors.

Do you know how to get PS to save in 4-bit?

OK, indeed that's a bit weird.
But after playing a bit, here's how.

When you index the image to 16 colors (Image/Mode/Index Color), and you select Local (Adaptative) in the drop down, the 16 for the colors, select primaries for the Forced dropdown. Next time you'll save your image as a BMP, you'll have the choice between 8 or 4 bits.

Ok, I was able to save to 4-bit using that method

I'll let you know in a while if the bootscreen works properly.

Ok, it now works, but I have a thick white border around the edges.

Also, the bootscreen shows for several seconds, and then it switches to a pure white screen for an equal amount of time before changing to the login screen.

what i had to do was save it as a 16 color gif through the save for webpage option. I then opened the gif and saved it as a 4bit bmp. sometimes i had to play with the color table.

Anyone know how to get rid of the white border and the white screen following it?

I would wait for the program to support more colors.

I did nearly the same thing apart from I chose "none" in the forced dropdown. If you select any of the other options it forces the palette to include colours you may not wish it to use. eg. if you select black and white it forces the palette to include black and white, or if you select primaries it forces the palette to use black, white, red, green, blue, cyan, magenta and yellow.

Except that if you select none in the forced drop-down, Photoshop doesn't give you the option of saving it in 4 bits, only 8 bits. Beats me why it does that, but that's how it is....

Not me.
I do the exact same steps, with the ONLY difference being the forced drop-down, and it only works if I select Primaries and Black & White. If I select Web or None, I only have 8 bits as an option when I select "save as..." and "bmp" for format.

ok, I just tested again and I think Local(selective) might be the actual setting...sorry for any confusion caused

Well, I just tested also, and weather I used Local (Selective), Local (Adaptative) or Local (Perceptual), I still don't have the option of saving in 4 bits if I select None for Forced... NEway.

Bump: I still can't make a bootskin.... still having the same problem as Aqua, outlined in an earlier post. Anyone know why the image is off centre and has a thick white border?
