Notes

If you're interested, here's the Macromedia action code for the Fwd button:

On (Release)
  Set Variable: "img" = img+1
  If (img<0)
    Set Variable: "img" = max
  End If
  If (img>max)
    Set Variable: "img" = "0"
  End If
  If (img<10)
    Set Variable: "str" = "flash_pics/000" & /:img & ".swf"
  Else If (img<100)
    Set Variable: "str" = "flash_pics/00" & /:img & ".swf"
  Else
    Set Variable: "str" = "flash_pics/0" & /:img & ".swf"
  End If
  Load Movie (str, "/ViewPort/View")
  Set Variable: "mes" = eval("message"&img)
  Set Variable: "picnumber" = str & " (" & mes & ")"
End On  

The only change for the Back button is:

On (Release)
  Set Variable: "img" = img-1
  :: ::
End On  

The JPG image button has the following action:

On (Release)
  If (/:img<10)
    Set Variable: "str" = "newpics/000" & /:img & ".jpg"
  Else If (/:img<100)
    Set Variable: "str" = "newpics/00" & /:img & ".jpg"
  Else
    Set Variable: "str" = "newpics/0" & /:img & ".jpg"
  End If
  Get URL (str, window="_blank")
End On

The initial frame has the following settings:

Set Variable: "str" = "flash_pics/0000.swf"
Set Variable: "message0" = "New Year's Day Lunch 2000"
Set Variable: "message1" = "Jamie, David and Me at the beach"
: : etc

Set Variable: "img" = "0"
Load Movie (str, "/ViewPort/View")
Set Variable: "picnumber" = str & " (" & message0 & ")"
Set Variable: "max" = "32"
