FYI: This list is for messages concerning development of Zope itself, not developing with Zope. Anyway, to answer your question, If the classes that your product defines support acquisition (the subclass Acquisition.Implicit or some other base class that does, such as SimpleItem.Item) then you can put the Images in the ZODB anywhere you like, so long as they can be acquired by the instances of your product class(es). Another idea would be to make your instances ObjectManagers (just subclass OFS.ObjectManager.ObjectManager) and the "webbies" can put the images directly in the instances. They would need to know what ids to use so that the dtml could pick them up properly. To make the dtml work without the images you can sprinkle in "missing" attributes so they fail gracefully if the image is not found: <dtml-var name="some_image" missing> Yet another idea (if the images are global to all instances of the product) would be to create a filesystem directory in the product (or anywhere on the server readable from Zope) that the webbies can save their image files directly into. You could then code the product so that it scans the directory and loads each image using the ImageFile method. The id could be based on the file name. Or, just make it pull them from the directory on the fly by defining a "getImage" method or somesuch that takes a file name, and loads it on demand. That way no code changes would be necessary to add new images to the product. hth, /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association [EMAIL PROTECTED] \---------------------------------------------------/ _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
