getting rid of images: remove_tags has no effect?

[Read&Write]

I am using the builtin recipe to acquire the rss from sueddeutsche.de. The recipe is very useful. However, I found myself unable to the articles from any graphical elements. I thought this could be achieved by inspecting the sites html and adding the specific elements to the remove_tags-list. However, this does not help. My workaround was to make the unwanted elements invisible using the extra_css option. Still, no sucess. Did I make some sort of gigantic mistake? After tinkering with the recipe for days and having learned quite a lot of useful things, I am stuck. I humbly request your help in this matter.

In order to get a better understandig of the problem, please refer to the following sources:

An example of an article that I want to strip the picture (along with its caption) from:
http://www.sueddeutsche.de/politik/2...tion-1.1392387

The recipe I am using. It is based on the builtin one called "Süddeutsche.de" and unfortunately includes all the images I want to get rid of:

I would be grateful for your help. I would definitely like to learn about this issue so I can avoid the problem in the future.

Your indentation is wrong. You need to indent remove_tags and extra_css four spaces so they become class members.

Thank you, that was the problem. The most basic of mistakes, it seems
