-- InfoboxImage, 20151209
-- Inputs:
--    image - Can either be a bare filename (with or without the File:/Image: prefix) or a fully formatted image link
--    ending - An optional parameter for the file ending, like gif, jpg, jpeg, png, svg.
--    endingdefault - An optional parameter for the default ending.
--    size - size to display the image
--    maxsize - maximum size for image
--    sizedefault - default size to display the image if size param is blank
--    alt - alt text for image
--    title - title text for image
--    border - set to yes if border
--    center - set to yes, if the image has to be centered
--    upright - upright image param
--    link - page to visit when clicking on image
--    suppressplaceholder - if yes then checks to see if image is a placeholder and suppresses it
--    usecaption - if yes then the caption from the image is used, else it isn't used

-- Outputs:
--    Formatted image.
