[Mediawiki-l] External script-generated images

[Sarunas Burdulis]

Hello,

Is there a way to embed (or enable embedding) of something that in raw
html would work as:

<a href="http://somesite.net/somepage.html>
<img src=http://somesite.net/script?param>
</a>

where script?param outputs an image?

Thank you,
Sarunas
