Ideally I’d like all the images within a post to be the width of the featured image. I’m obviously doing something wrong but when I upload a large image say 2448 x 2227 I am presented with several options – Thumbnail 150 x 150, medium 329 x 329, large 1024 x 1024, actual size and then custom.
The featured image size is showing as 685 x 458 (natural 777 x 520). My problem is that when I set the custom image option to the featured image width (height auto) the image ends up grainy and out of focus.
Currently I am using a medium setting but I’d much prefer the images to be the size of the article. I don’t understand why a large item looses quality when condensed?
