-- Inputs: -- image - Can either be a bare filename (with or without the File:/Image: prefix) or a fully formatted image link -- page - page to display for multipage images (DjVu) -- 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 -- suppressplaceholder - if yes then checks to see if image is a placeholder and suppresses it -- link - page to visit when clicking on image -- class - HTML classes to add to the image -- Outputs: -- Formatted image. -- More details available at the "Module:InfoboxImage/doc" page  local i = {}  -- List of placeholder images and tracking categories stored in [[Module:InfoboxImage/data]] -- Other constants: -- the system-wide default thumbnail size (in px) local defaultThumbnailSize = 250  -- If page is not a user page, return tracking category.
