Sending variable to flash page problem?

Hello, I have code in asp for send the name of the image to flash page like

                           galleryimageL=Request.Form("galleryleft")
	galleryimageR=Request.Form("galleryright")
	galleryimageF=Request.Form("galleryfront")
	galleryimageB=Request.Form("galleryback")
	
	if galleryimageF="" then
	galleryimageF=session("newFileNameF")
	end if
	if galleryimageB="" then
	galleryimageB=session("newFileNameB")
	end if 
	if galleryimageL="" then
	galleryimageL=session("newFileNameL")
	end if 
	if galleryimageR="" then
	galleryimageR=session("newFileNameR")
	end if 

I have first the galleryimageL/R/F/B for receiving the name from the former form. newFilenameF/B/L/R are the image name received from former upload function. Now when I use
if galleryimageF="" then
galleryimageF=session(“newFileNameF”)
end if
etc, it works well, but when I go back to choose nothing and proceed, the former uploaded image names are still show on the flash page.

How should I do to make it ,because I cannot use session.abandon due to I have login session id still there.

I wonder in which way I can receive the newFilenameF/B/L/R variables from the former page and send it to the proceed page without using session variable? Thanks!

Create hidden form fields on the page and pass them through like that…
