Talking Improving derStandard-recipe - how to get cover image?

Hi!

I am currently improving the recipe for the Austrian newspaper "Der Standard" (http://derstandard.at).

I already added some news feeds.
Now I try to change the standard cover image to the image stored on this page:

http://epaper.derstandarddigital.at/

This should work with something like:
Code:
def get_cover_url(self):
...
The problem is, I cannot find a concept for the images name (which changes every day).

Today the image can be found at
http://epaper.derstandarddigital.at/...5362970255.png
but tomorrow it will be a different URL.

How can this be achieved?

Thank you in advance!

By the way, here is the improved .recipe:
