 * Egyptological Museum Downloader Bookmarklet 
 * v. 1.5 (16 July 2023)
 * 
 * The aim of this bookmarklet is to facilitate downloading images of Egyptian 
 * objects from the websites of major museums. 
 * 
 * Usage: 
 * 1) Click on the link below and drag it to your browser’s bookmarks bar
 *    (also called 'favorites bar' in some browsers).
 * 2) Open an object page of an online museum catalogue, which contains images
 * 3) Press the link 'Museum Downloader' on your bookmarks bar. 
 * 4) Depending on the museum, the tool will either download all available images
 *    or open all images in new tabs.
 * 5) Your browser may ask if you allow the website to download multiple files 
 *    or to open multiple pop ups. If you do not allow, the bookmarklet does not 
 *    work. However, you only have to allow once, for each museum.
 * 6) Look in your downloads folder.
 * 
 * The bookmarklet downloads images from the British Museum, the Boston Museum 
 * of Fine Arts, the Louvre, National Museum of Antiquities (Leiden), Petrie 
 * Museum, Egyptian Museum (Turin), Royal Museums of Art and History 
 * (Brussels), Manchester Museum, National Museums Scotland (Edinburgh),
 * and the Bible and Orient Museum (Fribourg).
 * 
 * It opens all images in new tabs for the Brooklyn Museum, Metropolitan Museum,
 * Oriental Institute Museum (Chicago).
