 // GetPoster assembles an image, a caption line, and a
 // variable amount of descriptive text into a new
 // window. The parameters govern (1) raw Itemcode used
 // for special bookmarks in the page's hidden memo text;
 // (2) ItemCode converted to lowercase, used to assemble
 // the filename for an image file; (3) fixed length
 // (41-char max) item description converted to uppercase,
 // used as caption for the image; (4) window properties; and 
 // (5) 3-char file extension for the image file (e.g. 'jpg' or 'gif').
