UPDATED - Works with 4chan X!
Changes and Fixes:
- Download continues after deleted images are encountered. Thanks for the tip, Google User.
- Extension attempts to close new tabs that it has opened.
- Added support for 4chan X (with default settings).
Click a link to download every image in a 4chan thread.
NOTE: If you have the "Ask where to save each file before downloading" option
enabled in Chrome's settings, Chrome will open a "Save As" dialog for every
image in the thread, which may cause Chrome to crash. Please consider disabling
that option to use this extension, or temporarily disabling it when you wish to
download a thread.
