I'm on android, no ad blocker. The gallery was unusable for me because the photographs appeared in a modal that had a banner ad in the top, kicking the description off-screen after reflow, with no way to scroll. Had to switch to desktop view and zoom in on the photographs individually.

If you don't want people to use ad blockers, try taking UX seriously. Ads on sites like these are notoriously abusive to the users. I have no sympathies for their complaints about people blocking this crap.

Use uBlock Origin. Works fine here. Not sure what you are using.

I'm using AdBlock and I saw the modal too. I'll give uBlock Origin a try instead.

Or shown them how their content is not worth exposing your browser and brain to ads to.
