To further reduce the amount of traffic, please use another proxy-PAC:

Then, black/white graphics will be downloaded only.
We have an AddOn for Firefox now !
You can download from here
Using that AddOn allows you to activate/deactivate slimbrowse with a left click on the icon in the AddOn bar. And a right click opens the setup menue.
When you point with the mouse onto an image, and then right-click, a menue opens. Clicking on the slimbrowse icon in the menue displays the real image.
