The code below will find all flash (swf) files in a folder and then will convert them into GIF images with the same name and .jpg extension

' This example converts all SWF files in the folder into GIF image files
' Copy this script to the folder with SWF flash movies and run it
' Script will generate GIF image files using extracted frames from SWF

Set SWFToImage = CreateObject("SWFToImage.SWFToImageObject")

SWFToImage.InitLibrary "demo", "demo"

Dim WshShell, fs, f, fc, f1, tsFile
Set WshShell = WScript.CreateObject("WScript.Shell")

sCurrentFolder = WshShell.CurrentDirectory

Set fs = CreateObject("Scripting.FileSystemObject")
Set f = fs.GetFolder(sCurrentFolder) ' current directory
Set fc = f.Files
Set fs = Nothing

' converting SWF files to JPG image files
For Each f1 in fc
if UCase(Mid(f1.name, InstrRev(f1.name, ".") + 1)) = "SWF" then
SWFToImage.InputSWFFileName = f1.name
SWFToImage.FrameIndex = 1 ' number of frame to extract
SWFToImage.ImageOutputType = 1 ' set output image type to GIF (0 = BMP, 1 = JPG, 2=GIF)
SWFToImage.Execute
SWFToImage.SaveToFile Mid(f1.name, 1, Instr(f1.name, ".") - 1) & ".gif"
End If

Next

Set SWFToImage = nothing

The script code will convert every SWF file into GIF image in the same folder:
