[Typo3] manipulate contentelements by TS

[Carlos Rodriguez]

Hello,

i have a normal textpic element im my page.

How can I manipulate this?
I do *not* want to have the table arount the image when using
text w/image.

I created and extension template on the page and I tried to get through 
by jst testing to wrap the thing with:
tt_content.textpic.stdWrap.wrap = <div> | </div>

But this did not work.

What do I miss?

Any help highly appreciated!
=)

Thanks
