Hi all, I am starting to figure out things about Zope. And to this problem I have not yet figured out an answer: I have a lot of metadata about photos stored in a MySQL database. I have developed a Zope interface to show the metadata per picture using Zope and it works fine. I store small thumbnails in Zope for some, but not all the pictures. The thumbnail files have the same id as the MySQL variable idnumber which I show on the screen together with other metadata. My problem is that I cant figure out how to a/ test if there is a thumbnail file for the idnumber variable and b/ if so - show it together with the metadata - and if not - show a dummy picture instead I have tried many things but it seems impossible to have Zope test if the contents of the <dtml-var idnumber> variable can be used to check the exsitence of a possible thumbnail file with the same name. Is there a solution? Best regards from sunny but rather cold Stockholm, Ebbe _____________________________________________________________ Här börjar internet!
