For www.fromoldbooks.org I use an external program "remaneimagesbysize" that makes file with name like "flint-castle-306x500.jpg" containing the width and height in pixels, and then I can use string processing in XSLT and XQuery. That and scanning a list of files in a directory to see which are images, extracting EXIF metadata, and getting modified dates. I should resurrect the proposal. -- Liam Quin - XML Activity Lead, W3C, http://www.w3.org/People/Quin/ Pictures from old books: http://fromoldbooks.org/ Ankh: irc.sorcery.net irc.gnome.org freenode/#xml Co-author, 5th edition of Beginning XML, published by Wrox, July 2012
