On boost you need to enable HD images before its readable. I assume it's the same for other apps.

Viewing via kbin on Firefox mobile, the interface just automatically makes the image fit the width of the phone, it's longer than the screen but that's what scroll is for, everything perfectly readable. If I had to guess I'd say that's a kbin feature over a Firefox feature, but could be a combo of the two.

I slogged through the whole thing and now that I'm reading the comments it's decided to go full crisp hd. A little earlier would have been nice...

Needs way more JPEG.

Looks fine to me if I zoom in, probably an issue with your client

On web you can get the full resolution by clicking the title instead of the image.

ctrl +

Zoom has been a function in nearly every mobile and computer browser for well over a decade at this point...
