I’ve made some changes to the script to scrape from different sources (http://kiosko.net, http:/nytimes.com, http://elpais.com) and other sources can be added easily, for each source there are two methods,
save_source_issues, the first method is to construct the URI of the issue image based on some pattern which different from source to another, and the other method is to scrape the images and save them on the disk in their specific folders. I’ve wrote some comments to clear some parts of the code.
Note, to scrape from specific source you should comment the others as you can see in the code, for example to scrape from New york Times you should un-comment line 15 and line 32 and comment line 14 and line 31, and also if you want to run the script on https://scraperwiki.com/ you should comment line 3 and don’t try to scrape from elpais because scraperwiki don’t have “RMagick” gem installed.
