Still works
That was a pleasant surprise. Still works and did a good job upscaling the image thumbnails.
It’s still relevant god damn it
Whaaaaat? You don’t use this plugin? It’s good.
Not working 100% anymore
I’ve been using this great plugin for a number of years with no problems. It still works for some images but I have been getting blank images returned. I believe it’s something to do with the srcset p
