Input Vertical Banner (120 x 240) Adsense Ad Into Middle Of Post. Possible?

Hi guys,

As stated in the topic title, is it possible to let adsense display, in such a way, in the middle of a post? It’s just that I’ve seen some sites able to do this, so I’m wondering if it’s possible to do this in a blog entry.

Something like this:

blah blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah blah
blah blah blah blah blah
blah blah blah blah blah
blah blah blah blah blah
blah blah blah blah blah
blah blah blah blah blah
blah blah blah blah blah
blah blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah blah

The empty space is where the adsense ad will occur. Something like that. ??

Although I’m not really well-versed in PHP, I’m willing to learn if someone is kind enough to provide some specifics. But if it’s not possible, then so be it.

I’ve turned off the WYSIWYG editor, by the way.

Any ideas?
