FLASH: Weird transparency problems

[Rebecca Lovelace]

We have some bitmapped art that needs to be transparent.  We tried exporting

as Gif 89a from Photoshop with a transparent colour, but are getting some

bizarre effects.  Originally, each piece of art was saved with its own

adaptive palette, so I thought perhaps that was the problem, so I tried

converting everything to 256 Mac system palette.  Instead of being purely

transparent, the background colour is translucent and some random colour (on

one piece it's green, another it's purple, another it's light green)...

changing whether compression is JPG or PNG seems to have SOME effect, but

the whole thing makes me rather nervous.  I get this right in Flash, and if

I test the movie or publish it, I get varied strange effects.


Is this a known issue?  Why is it happening?  What could I do with this

artwork to get around it?


Thanks!!


Rebecca
