When I first started playing with PNG I noticed this too going from 

Photoshop to Flash, but I found that exporting PNG files from 3D Studio 

Max into Flash it would support the Alpha Channel. After much head 

scratching I figured out what was happening.  Photoshop does not 

automaticly turn the Alpha Channel on, so even if you export an PNG 

image from photoshop with a transparent background, unless it has the 

Alpha channel turned on, it will not come out as 

Transparent/Translucent.  So here is how you do it...


Make your photshop image, and float/Select the opaque part of the 

object. (The quick and easy way is to hold down the CTRL key and click 

on the layer to be selected in the layers menu)  then go to the Channels 

Menu and "Add Channel"  This should default to "Alpha".  The Alpha will 

come out as black but the "Marching ants" selection should still stay 

current.  Fill that selection with White.  Now Make your RGB Channel 

visible again, export as a PNG file, import into Flash, and voila!


FWIW I have noticed that there is some sort of Gamma correction problem 

between Flash and photoshop as PNG files from photoshop loose contrast 

and get VERY dark, so you'll have to lighten it up and up the contrast a 

little before exporting from photoshop.  Hope this helps...
