The Item property contains details of an image contained in the graphic. Some file formats allow multiple images to be stored within one file. For instance Photoshop files may contain multiple layers. TIFF files may contain multiple images at different resolutions. In this case you can reference the second image in this way.

[VBScript]
Set gr = Server.CreateObject("ImageGlue7.Graphic")
gr.SetFile(Server.MapPath("layers.psd"))
h = gr.Item(2).Height
Response.Write("Height=" & h)

Note that the first item is the default image (e.g. the composite Photoshop image) and subsequent items are additional images (e.g. individual Photoshop layers).
