Best way to create thumbnails?

[RGould8 at aol.com]

I've got an app which I've written (quite rapidly thanks to Revolution), 
which allows the user to drag-and-drop JPEG images from their hard-drive, and it 
automatically uploads them to a central repository known only to the app.   
This is working great, but I'd like to do one more thing - - - I'd like to see if 
it's possible for Revolution to create a thumbnail image of each JPEG image 
that's getting uploaded, and place the thumbnails within another directory on 
the server.

I'm looking for advice as to the best way to accomplish this - - - since I'm 
just FTPing the images right from the hard-drive to the server, I'm not 
actually opening and reading the image files.   Should I assume that I need to alter 
this strategy and have Rev open each image file before it gets uploaded, and 
take a snapshot of each image and shrink it and save it out as a thumbnail 
JPEG - - - then FTP both the full-size image as well as the thumbnail image?   
There's no "create thumbnail from JPEG" command that I've missed in Rev is 
there?
