Adding explicit thumbnails (featured images) to your content takes time. Even if you don’t add your own photography, you’d still need to go to search.creativecommons.org or so. This plugin hooks into the thumbnail URL and changes this with an image from the Flickr API, based on the tags in your post. If Flickr couldn’t find anything, it will return an empty string. I have achieved good results, with posts that all of a sudden had a rather adequate thumbnail.
[Flickr images might have licensing issues, so I recommend to use this plugin only on personal sites]

Flickr Fallback Thumbnail

Automatically grab a fallback featured image if your post doesn't have one!

WordPress has the function wp_localize_scripts for translation, but the strings passed to it have to be hard-coded. Until you parse the .js-files and scan for occurrences of _e() with a fast regexp, and localize them with the data using the WordPress _e-function to localize from a .po file. *Note*. Your po-file has to include strings from javascript files. To do this in Poedit, see http://stackoverflow.com/questions/16557327/how-to-generate-po-file-from-js-file-using-poedit.

Localize js

Provide translation function _e("") in javascript files.
