Path = "C:\test.jpg"
arr = Split(Path,"\")
FileName = arr(Ubound(arr))
FolderPath = Left(Path, Len(Path) - Len(FileName) - 1)
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace(FolderPath)
set objFolderItem = objFolder.ParseName(FileName)
Width = objFolder.GetDetailsOf(objFolderItem, 162)
Height = objFolder.GetDetailsOf(objFolderItem, 164)
Msgbox "Width: " & Width & " Height: " & Height
