yup. when you call the image, you get a complete img tag. And when you insert text in tal, it gets quoted unless you use "structure". So you could do a couple of things: 1. Get the url instead of the complete tag: <img src="../images/ldmlMenu_01.png" width="170" height="2" border="0" tal:attributes="src here/images/ldmlMenu_01.png/absolute_url"> 2. Use the complete tag: <img src="../images/ldmlMenu_01.png" width="170" height="2" border="0" tal:replace="structure here/images/ldmlMenu_01.png"> or <img src="../images/ldmlMenu_01.png" width="170" height="2" border="0" tal:replace="structure here/images/ldmlMenu_01.png/tag"> -- Paul Winkler http://www.slinkp.com Look!

The *definitive* reference is [drumroll] the source. If you read the source -- even just the method definitions -- of the Image object (which is, by the way, is with File in OFS/Image.py) and its parents, you will know exactly what it can do. And yes, I know that's not what you wanted to hear. The Zope API reference, either from the online help system or from the appendicies of the Zope Book, is often very useful. In the case of the Image, it would have told you exacty what you wanted to know. In other cases it is less than useful, such as with the fictional ObjectManagerItem. Perhaps by fiddling with pydoc or DocFinderEverywhere we can get a better API reference. I haven't tried yet. --jcc
Simon: The tal:attributes="src here/images/ldmlMenu_01.png" is actually replacing src with the default view of an image which is the html tag itself. An *easier* way of doing what you want to do would be: <img src="#" alt="#" tal:replace="structure here/images/ldmlMenu_01.png" /> This will replace the <img [...]> tag with <img src="http://127.0.0.1:8080/ldml/images/ldmlMenu_01.png" alt="" title="" height="2" width="170" border="0" /> The tal:replace command replace whatever tag it resides in. The "structure [...]" will tell Zope not to escape characters (ie " == "). hth, Andrew Williams "Simon Forster" <simon-lists@ldml.com> wrote in message news:C62CE791-A1BF-11D7-9ACC-000A9579123A@ldml.com...

Calling an Image gives you a complete <img> tag for that image. To do what you want, use either of these: <img src="../images/ldmlMenu_01.png" width="170" height="2" border="0" tal:attributes="src here/images/ldmlMenu_01.png/absolute_url"> <img src="../images/ldmlMenu_01.png" width="170" height="2" border="0" tal:replace="structure here/images/ldmlMenu_01.png"> Cheers, Evan @ 4-am

Just to add to the pile... if you really wanted that very string to be used (and you don't, you want the path, which is a method on that object), you would say something like <img src="../images/ldmlMenu_01.png" tal:attributes="src string:here/images/ldmlMenu_01.png"> to keep it from being interpreted by Zope. Not that this is used much, but still. --jcc
