Sorry, the "missing" attribute doesn't work, but you can always just wrap it in a <dtml-try> block that will catch the error and not do anything with it, like <dtml-try> <dtml-var expr="_[id()+'.gif']"> <dtml-except> </dtml-try> It's a bit of a kludge but it works.

Genius! It works both, maybe complicated one will work better (restricted acquisition), but...

But it does have error when filename does not have image filename.gif, like file2

I was try dtml-if, dtml-let+dtml-if (and nested dtml-in - it does not work because one is ObjectValue"DTML Document" and second is ObjectValue"Image").

<dtml-if "_.string.find(_.getattr(this().aq_parent, id() + '.gif'), '.gif')>0">

In attachment is a small file with my some tryouts (sorry, You do not an idiot, but me :)

Many thanks
