Here's what works, in case anyone else is interested in, for example, having a random banner-image behind some fore-ground text: Each image is displayed on its own page as the background behind an (:include ...:) statement, where the material that's included is [[#anchor-tagged]] fore-ground text (maintained wherever that's maintained). So there's a page for each image, and all that's on each page is the image behind the included text, like this: (:div style='border:4px groove #99f; padding:10px; background-image:url([=http://www.mysitename.com/Test/HomePage?action=download&upname=ImageNameHere.jpg=])':) (:include Test/TextPage#incl#inclend:) (:divend:) THEN on Test/ImageRotation, I have (:pagelist group=Test order=random count=1 fmt=#include name=-TextPage,-Template,-HomePage self=0:) It looks like the other version of random-inclusion would work this way, too, if all the backgrounds were displayed, with included fore-ground text, on a single page, each demarcated by [[#anchor-tags]], and then the randomizing code could be (:include {Groupname/Pagename$RandomSection}:) -- per the recipe at http://www.pmwiki.org/wiki/Cookbook/RandomQuote (unless there were a problem with tagged sections inside tagged sections, and including an inclusion). But in any case, it's all too messy for most non-programming authors to be asked to do - what with having to remember all the rules for formatting, sizing, naming and displaying the images and including the fore-ground text. _______________________________________________ pmwiki-users mailing list [email protected] http://www.pmichaud.com/mailman/listinfo/pmwiki-users
