[Zope] Q: How can i check the existence of an image?

4 Jan 2002

      Hi Zopes,

How can I check the existence on an image file in my image folder. I
coded a workaround, but it doesn't fit my needs exactly:

<dtml-let myTemp=id> 

'Build the image file name

<dtml-let MyID="'theme_'+myTemp+'.gif'"> 

 'loop over each image in the image folder

<dtml-in expr="images.objectValues('Image')">

' String find

<dtml-if "_.string.find(id(),MyID) > -1"> 

' -> if there is a matching file print image in HTML
<img src="/images/<dtml-var id>" width="145" height="129"> 'print image
in HTML

</dtml-if>
</dtml-in>
</dtml-let>
</dtml-let>

...but I'm looking for something like this:

'check if true or not
<dtml-in expr="images.<image_name>"> 

TIA
