I have RH Linux 7.1, Zope 2.4.1 (fresh install), and I can't seem to import images into my site (I haven't tried other objects). For example, using the management interface, I created a folder "test folder". I enter the folder and click on Import/Export button. I enter a filename (ie, somefile.jpg) in the "Import File Name" box. The "Take Ownership" box is checked. (The file exists in the /usr/local/zope/2-4-1/imports sub-directory.)  And then I get the following output. You may assume I'm a Zope idiot and explain import/export in words of one syllable or less. For example, do you have to add the files to the import directory in some special fashion? I just copied them into there from the BASH shell command line (not in Zope). Thanks, Mike
