How to Update External Images in Flash
Imported images often need editing once they are in the library. The Update button in the image dialog box allows you to reload your externally updated image file. Once updated, the authoring environment and rendered swf movie reflect the changes.
Select a keyframe on the timeline and add an external image to the stage by selecting File > Import > Import to Stage (Cmd/r (PC-Ctrl/r)).
Using Photoshop, open the original file and edit the file (i.e., levels, convert to black and white, etc.).
Save your changes (File > Save) and close your image file.
Returning to Flash, open the Library (Window > Library).
Double-click the bitmapped image icon to open the dialog box.
The dialog box provides information about the image such as its location and size.
Click the Update button and the image is reloaded into Flash with the recent changes.
