@jonaballen Thx for the detailed response. As long as you state it I have to believe you now 😛 , I should do some better tests I guess when I'll have more time as from those that I did in quite a hurry in the summer where I was needing a good data saving but without breaking everthing like Opera Mini's extreme mode does, it proved out that by disabling the images with opera for android the data usage was about the same or just very insignificant less than Opera Mini's on high savings with images on low, which was pretty wierd.
P.S. Out of genuine interest why is disabling images not an option for Opera Mini as well (on high savings of course not on extreme) is that a webview limitation?
