CMS article preview image via PHP

[Julchen]

I created a dynamic PHP page as an article, so to be able to load several images from the database. That part worked beautifully.

Now I'm trying to also use one of those images as a preview image.
Yet
<img src="http://www.domain.de/images/1.png" class="cms_article_preview_image" />
won't accept any dynamic input.

I'd love to do something like this:

<img src="http://www.domain.de/images/selectimage.php?<?= vB::$vbulletin->nodeid ?>" class="cms_article_preview_image" />
 

Any hint on how to tweak vB into doing what I want?

Thx
