Adds an image to a spreadsheet.

addImage( workbook, filepath, anchor  );
addImage( workbook, imageData, imageType, anchor );

• workbook spreadsheet object
• filepath string: absolute path to the image file OR
• imageData image object AND
• imageType string: Possible values: "dib", "emf, "jpeg", "jpg", "pict", "png", "wmf"
• anchor string: Where to place the image expressed as a list of either 4 or 8 numbers:
• [startRow],[startColumn],[endRow],[endColumn]
• [startXPosition],[startYPosition],[endXPosition],[endYPosition],[startRow],[startColumn],[endRow],[endColumn]

Chainable? Yes.

• The first anchor format specifies only the row and column numbers, the second also specifies the positions in the cell using pixel X and Y coordinates relative to the upper left corner of the cell. If you use the first format the image corner positions within the top left and bottom right cell are 0,0 and ,0,255.
• The endRow and endColumn values are not inclusive and therefore should be higher than the startRow and startColumn values. Your image will not appear if the start and end values are the same.

spreadsheet = New spreadsheet();
workbook = spreadsheet.new();
path = "c:/temp/picture.png";
spreadsheet.addImage( workbook=workbook, filepath=path, anchor="1,1,2,2" );// place in A1 (first column, first row).
