Rinomina file Upload

[salvobello]

Salve a tutti!
Avevo già chiesto se qualcuno sapesse aiutarmi ma non trovo risposta ... quindi riprovo.

Ho bisogno di fare un upload on line di un file immagine e, in caso venga trovato il file con lo stesso nome gia presente nella cartella publiue/immagini rinominarla come nomeimmagine(numeroProgressivo).jpg

Sapete aiutarmi?

Grazie a tutti!

Due soluzioni:

1. memorizzi i dati in un db e fai un normale controllo;
2. esegui un controllo tramite FSO.

Volevo eseguire un controllo FSO ma non l'ho mai fatto.
Sai aiutarmi?

Questo è il linguaggio che uso:

Class FileUploader
	Public  Files
	Private mcolFormElem

	Private Sub Class_Initialize()
		Set Files = Server.CreateObject("Scripting.Dictionary")
		Set mcolFormElem = Server.CreateObject("Scripting.Dictionary")
	End Sub
	
	Private Sub Class_Terminate()
		If IsObject(Files) Then
			Files.RemoveAll()
			Set Files = Nothing
		End If
		If IsObject(mcolFormElem) Then
			mcolFormElem.RemoveAll()
			Set mcolFormElem = Nothing
		End If
	End Sub

	Public Property Get Form(sIndex)
		Form = ""
		If mcolFormElem.Exists(LCase(sIndex)) Then Form = mcolFormElem.Item(LCase(sIndex))
	End Property

	Public Default Sub Upload()
		Dim biData, sInputName
		Dim nPosBegin, nPosEnd, nPos, vDataBounds, nDataBoundPos
		Dim nPosFile, nPosBound

		biData = Request.BinaryRead(Request.TotalBytes)
		nPosBegin = 1
		nPosEnd = InstrB(nPosBegin, biData, CByteString(Chr(13)))
		
		If (nPosEnd-nPosBegin) <= 0 Then Exit Sub
