<p>What's the url for its poster image?</p>

The URL is a random string as far as I can tell.
It can still be easily retrieved. It is the only
```
img
```
inside the anchor named
```
poster
```
.
So, if you are reading the source, simply search for
```
<a name="poster"
```
and it will be the text following the first
```
src="
```
from there.
However, you will need to keep the screen scraping code updated because that will probably change.
You should also be aware that the images are copyrighted, so be careful to only use the image under a good "fair use" rationale.
