Webmaster Forum / Flash / Flash Site Design / August 2007

Unfortunately, the Update option from the Flash Library panel does not, as you
have already found, update an individual layer from a .psd file.

The work around to this is to save your altered layer from Photoshop as its
own file.  Then, Update your library item and direct it to the new image file.

Ideally the updating method would behave as it does in After Effects; it would
be nice if this functionality was included in the next version of Flash.

Thanks for the response. Yeah I had kind of come to the same conclusion.

Also i've had some problems with file sizes, as you don't have as much control
in compression. For example if I have a largish simple graphic best suited as a
gif it imports i as a much larger file if I choose the lossless compression
mode than the same setting would be if i just imported the gif separately.

Ultimately I think that the lack of functionality and compression flexibility
will mean that I won't use this feature but continue to import all my assets
individually and re-build in flash. It looks the goods but just isn't quite
there yet ... maybe the next version of flash.
