Chrome browser extension to download images from photo album webpage?

There's a software Bulk Image Downloader at http://bulkimagedownloader.com/. I'd use this program if I really need it because I doubt if it's clean.

From their site:

BID web browser integration is automatic for Opera and Internet Explorer. FireFox and Chrome integration require extensions to be installed.

Save Time No more endless clicking and right clicking to "save image as..."

It just works No complicated configuration or project files need to be set up.

You're in control Preview images as thumbnails or in full size before downloading. Only download those you want.

Automated Downloads Queue up multiple galleries for automated unattended downloading with the BID Queue Manager. Great for TGP sites and web forums.

One tool for all sites Stop switching between different downloaders for different web sites. BID does them all.
