The absolute path/locator (used to complete the relative path) should be stored separately, I think.
I remember, the Image stores the absolute path (as a single field Name???), the relative path (as an attachment "fullFilePath"), the file name (as an attachment "fileName") currently. Why is the absolute path stored in the single field Name??? How about storing the file name as a field (it does not change and it does not depend on paths, for memory images it is just empty) and the path information (relative path and absolute path/locator) as attachments. Additionally, it would be helpfull for me to know all places in the current code, where name/path information is stored ;-) Regards, Christoph ------------------------------------------------------------------------- Using Tomcat but need to do more?
