Well you can download the FrontEnd mdb via XMLHTTP, Inet or URLMON.DLL.
Choose your poison.
After that it is just manipulating as a disk file.
Oh yes you can also use winHTTP object on Win98 and up

This gives you finer control in a class

Download files asynchronously with URLMON.DLL

or --------------

3. Add a MS Inet control to the form (Inet1)
4. Add a textbox (Text1)
5. Set the textbox Text property to
"http://images.ucomics.com/comics/ga/2003/ga030214.gif"
6. Add a command button (Command1)
7. In the Command1_Click event, add this code

    Dim strURL As String
    Dim bData() As Byte      ' Data variable
    Dim intFile As Integer   ' FreeFile variable
    Dim sFilename As String

    strURL = Text1.Text
    sFilename = "C:\Temp\" & Mid(Text1.Text, InStrRev(Text1.Text, "/") + 1)
    intFile = FreeFile()      ' Set intFile to an unused file.
    ' The result of the OpenURL method goes into the Byte
    ' array, and the Byte array is then saved to disk.
    bData() = Inet1.OpenURL(strURL, icByteArray)
    Open sFilename For Binary Access Write As #intFile
    Put #intFile, , bData()
    Close #intFile
