Just tried replacing the code. It works well. But I noticed that there are more images than was the case with the issue downloaded using the built-in recipe. (They all come from "blog" articles of TE like Charlemagne).
For example:
http://www.economist.com/node/21556949 (Charlemagne)
http://www.economist.com/node/21556983 (Myanmar)
With the built-in recipe, images in Charlemagnes of 2012 at the bottom were not downloaded (that's great, since they are just images from past column). But a series of news images in the article on Myanmar were downloaded. (which is also good)
However, with the modified recipe, both images of Charlemagne and Myanmar were downloaded. I can't figure out the reason since the modified version just took out the quote.
Is there a way to exclude images like " Charlemagnes of 2012" while including "Myanmar" at the same time?
