[Zope] Newbie question re referring to items

[Gupta, Anu]

Thanks for all the help guys...

Actually, I knew these techniques, but for some reason, they were failing. 

Suddenly I realised I had a different images folder one level up which was
being acquired rather than the images directory I wanted, higher up the
tree.

Moral - delete temporary folders before they bite you in the ass - and think
before posting. Still, maybe someone else will search on this one day, and
save 10 minutes of their time !

Did you read the Zope book or

Background reading will tell you about the following options:

   *   "<dtml-with images><dtml-var myimage></dtml-with>"

   *   '<dtml-var expr="restrictedTraverse(path_to_your_image)">'

   *   '<dtml-var expr="images[name_of_your_image_as_string]">'

   *   '<dtml-var expr="images.your_image">'

Read a bit, learn about the various restrictions
and select the best alternative for you.
