So you’re working on a Flash project with l-o-t-s of imported bitmaps and you want experiment with various export settings.
Finally in Flash 10 you can edit the export settings for more than one library bitmap at a time. It used to be tedious to say the least adjusting them one by one if you needed to change many.
However if you have Flash 9 ( or 8 ) you can add this extra functionality yourself by creating a custom control using the extendable jsfl api that Adobe products have. I’m sure other people have made things that can do this, but I couldn’t really find what I needed, so I decided to make one myself which may be of use to others. Also included is the source fla if you want to see how it works.

This video tutorial by Lee Brimelow is a good primer on how to make your own custom Flash panels. If you haven’t made one already, it’s much easier than you might think.
Instructions: Download the zip and put the enclosed ‘Bitmap Properties.swf’ file in one of the the following locations:
MAC:
[User]/Library/Application Support/Adobe Flash CS3/[language]/Configuration/WindowSWF
WIN:
C:\Documents and Settings\[User]\Local Settings\Application Data\Adobe\Flash CS3\[language]\Configuration\WindowSWF
After moving the file restart Flash and go to
Window->Other panels->Bitmap Properties
You should now see a panel ‘Bitmap Properties’ that will let you change the export settings for whatever bitmaps (or folders of bitmaps) are selected in the library in one hit. Enjoy!
