@leocg Is that because it’s a jpg image? I have uBlock Origin installed on a different device. When disabled all the ads display on that site as expected, when enabled they don’t (mostly). That’s without any special filters added.
On my PC I selected a couple of ads at japantoday.com and checked Network Filters in uBO. The difference between the 2 lines below is that the first one is blocked while the second one isn’t. So there must be some way of identifying them as ads but unfortunately it seems that Opera’s ad-blocker doesn’t have quite the same capability. It would be good if the devs could somehow incorporate that into the code in some future release?! Otherwise it would be handy if there was function to select and block certain images.
