Actually dots are allowed in object names. You can create a picture called 
"myPic.jpg" and insert it with <dtml-var myPic.jpg>.

However because of their special meaning in Python they make it more 
difficult to access objects in Python expressions from DTML.

Example, to access the picture title, you'd need to use :

<dtml-var "_['myPic.jpg'].title">

or (simpler but longer)

<dtml-with myPic.jpg>
    <dtml-var title>
</dtml-with>


Cheers.
