It wasn't clear to me from the App's description (though in retrospect I don't know why), but it was easy to go to the App's web site linked under the App's description and use the "Advance Web Editor" to create a filter to block all images from loading on my browser. Not that you would want to do this, but when I'm running low on data it can be nice to still use the browser. It was easy to create, downloaded to the App, and was done in less than a minute. I was surprised and glad I didn't have to get some separate browser app to do it.
All else seems to work perfectly too. I just turned on the filters that I wanted and forgot about it.
