Despite reading the page, I still have no idea how it actually works. Is this an advanced version of thumbnails, only to put multiple pictures in one only thumbnail mark, and navigating among them with "<" and ">" buttons?

@Searcher200 The default tiff handler only support a single image. But tiffs can also contain multiple images in the same file. Just like a PDF. This extension provides functionality to recognize that there are multiple images in the TIFF and to use all these images, by providing support for a page= parameter for the transclude syntax and pagers < > on the file description page.
