I had been using {File.MD.Composite\ImageSize\ImageSize\0} to display width x height in pixels, but it appears that it isn't imported any more. There are often camera specific fields, but I want something that works for all images. Can this field be imported please?
(I know that IMatch has separate width and height fields that it stores, but I was hoping for a combined field.)
