I don't think that you can open flash files in photoshop

And I don't know if other program could do. As far as I know, you can produce flash files in Director bat files like yours can not be opened and take images back from them.

Although a solution you can use is to "capture" the image with the print screen faction, explaining:

ran the flash file
and when you see the picture you like, hit the "print screen" button (key) on your keyboard, it is somewhere at the upper right corner on keyboard, normally next to "scroll lock" key. The text on the key that you are looking fo is "Prt Sc" or something like that.

Next go to photoshop, select new file from file menu,
and when new file opens, select paste from the edit menu, and you see your screen of when you used the print screen.
Now you only have to crop the image from flash out of the whole image.

good luck
