[TYPO3] Page content in div marker

[Oktawiusz Poranski]

Hi

I'm trying to add a random picture on my page as a left side block
I'm not using TemplaVoila on my site.
Since i'm quite new to TYPO3 i would like to ask if there is a way to 
display page content by TS?

For example as marked subpart in html template file like:
In html template file:
<div id="randomimage">RANDOM IMAGE HERE</div>
and in template:
subparts.randomimage = ???(page id=5 content)

Is it possible? Can anyone point me in right direction?
