I like using double_click to get to things, like a double click to bring up the image on a form in some Windows image app (the default one).
How about Shift + double-click to see the path to the image (or whatever)?

Add these lines to the appropriate places in your code:
In your form helper module:
{Public Declare PtrSafe Function GetKeyState Lib "user32" (ByVal nVirtKey As Long) As Integer}

In your code for the image or document control:
  {Dim ShiftPressed As Boolean, CtrlPressed As Boolean}

{  ShiftPressed = (GetKeyState(16) And &H8000) <> 0
  CtrlPressed = (GetKeyState(17) And &H8000) <> 0
}

{  If ShiftPressed And CtrlPressed Then
  ElseIf ShiftPressed Then
    If IsFolderOpen(FilePath) Then
      AppActivate FilePath
    Else
      Shell "Explorer.exe " & FilePath, vbNormalFocus
    End If
  ElseIf CtrlPressed Then
  Else
    If Not IsNull([ID]) Then
      FileName = FilePath & LTrim(Str([ID])) & ".jpg"
      If Dir(FileName) <> cZls Then
        Call sDoOpenLink(FileName)
      End If
    End If
  End If
}
