Hi, I just did came across this today and found an answer.. I am calling a SQL database, getting back a variable "image_name" and checking to see if that name of that variable exists as an image. "image.merchants" are the folders I am keeping the images in... (nested) <dtml-if "_.hasattr(images.merchants, image_name)"> # if it exists <dtml-var "_.getattr(images.merchants, image_name)"></a> # display it <dtml-else> # otherwise Some other thing to do (I used a text link) </dtml-if> Hope this works for you... If anyone knows how to get the border to ="0" when getting back that image I would apprecitate it. JMA

Hi,

We have a sql database with employee information. Every employee record has an MWID field. Photo's of the employees are stored in a Zope folder (mwfoto) where the id of every photo has MWID as its name. So we can display the photo like this:

<img src="/psychologie/mwfoto/<dtml-var mwid>"

This works fine. Now I want to check if a photo exists, and if not, display some other info. In some sort of Zope pseudocode:

<dtml if exist(mwid)> showphoto <dtml else> showanotherveryinterestingpicture </dtml-if>

How do I do this?

Your help is very much appreciated,
