I don't even have/use Photoshop.
I use Jasc Paint Shop Pro 7.
This is what I do all the times:
- in case servimg not working for you...:
1 ) open the original image
2 ) lower it to 256-color
3 ) set transparency color (I use 255 0 255 most of the times)
4 ) save palette (*.pal file)
5 ) use text editor to open the saved palette
6 ) move the transparency color 255 0 255 to the palette index color:
Before change:
- Code:
-
JASC-PAL
