How does it work?
1. Click on Browse to select a folder containing the swf files.
2. Wait for the right moment and click on "Snap" to create the snapshot. The snapshot is automagically saved in the same folder as the .swf under the same name (except it's a .jpg file). You will also hear a sound to confirm the snapshot.
3. Click on "Next" to advance to the next banner. The progress bar is an indication on what .swf file you are currently at. The status text below the buttons also shows what file you are currently at.
The file is a standalone executable, no need to install it.
