Good when it works

I’ve been using this plugin for a long time but unfortunately I can no longer recommend it, as there have been quite a few technical problems with it, particularly I think since it was bought up a while back. For example, currently lazy loading is broken (causes incorrect thumbnail proportions on mobile, or cropping not to work), so you have to turn it off. That in turn for some reason messes up the srcset markup, so downloaded thumbnails are way larger than they should be, which has caused serious problems on my site. There has just been an update but it has not fixed it. They don’t issue changelogs either.
