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:

@kovidgoyal:
Thank you for your answer. I did search for a link a bit, but didn't find one.

I hoped there is a way like this (in pseudo-code):
Code:
OPEN URL "http://epaper.derstandarddigital.at/";
coverElement = (SEARCH HTML-ELEMENT "<img>" WITH ID "imgPage2" AND CLASS "page");
coverUrl = (GET HTML-ATTRIBUTE "src" FROM coverElement);
RETURN coverUrl;
Wouldn't that be a way?

Is there another place to upload this recipe, so that it can be added to the next release of Calibre?

Thank you for your help and for Calibre
