Convert file command in Graphic Converter.....help

Question

OK, I'm a software engineer by trade, so I'm sure I'll get the hang of AS, but I have to admit, I'm having problems getting started.
I would like to create a simple drag/drop Applescript that will invoke GraphicConverter and perform a predefined file conversion process. Specifically I want to convert dropped images to the Electric Image "IMAGE" format.
I have looked at all of the sample scripts on numerou sites, and they use the "Save Window" method. I would like to use the "Convert File" method.
Any sample code that may help me with this? I've looked at the AS Dictionary for GC, but I'm not sure where to proceed. Here is the text from the dictionary:
convert file v : convert a file using a batch setting to the destination folder
convert file
using batch file specification : batch settings file
to folder file specification : destination folder
Thanks for any help!

No error checking is provided.
Only graphic images are assumed to be dragged onto the applet - whose code is provided below.
on open (dragged_Images) -- Handle users action to drag images onto applet.
my handleDragged_Images(draggedImages)
end open
on run {} -- Handle users action to open (launch, run) applet.
say "Drag and drop images onto this applet"
end run
-- Handler (function) to cycle through selected images, saving each image as type 'IMG'..
on handleDragged_Images(localImages)
repeat with i in local_Images -- Cycle through the dragged images.
-- Obtain '.' extension of file.
tell application "Finder" to set tExtension to ((name extension of i) as string)
if (tExtension is "") then -- If no extension exists ...
set file_Name to (i as string) -- Create and set variable 'file_Name' here.
else
-- Create and set variable 'file_Name' here, without existing '.' extension.
if ((i as string) ends with tExtension) then
set {oAStID, AppleScript's text item delimiters} to {AppleScript's text item delimiters, "."}
set file_Name to get (text items 1 through -2 of (i as string)) as string
set AppleScript's text item delimiters to oAStID
end if
end if
-- Have 'GraphicConverter' open, save (as IMG file) and close file.
tell application "GraphicConverter"
open i
save window 1 in ((file_Name & ".img")) as IMG
close window 1 without saving
end tell
end repeat
end handleDraggedImages
