[JENKINS-76035] GitHub Organization avatar is blurry on HiDPI/Retina displays #1470
Description
Using a [HiDPI (aka Retina) display |https://en.wikipedia.org/wiki/Retina_display,] reproduce with the following steps:
- Under a GitHub Organization's Project enable avatar:
Projects > Repository Sources > GitHub Organization > Enable Avatar - Go to the project's page: /job//
- Look at the 48x48 pixel avatar on the top
Expected result: The avatar image shouldn't be blurry
Actual result: The avatar image is blurry/low resolution
It seems that the avatar image is fetched from GitHub with the same resolution as the dimension of the container:
https://avatars.githubusercontent.com/u/?v=4&s=48
I.e., 48 pixels wide for a 48 pixel wide img element. However, this is not sufficient resolution for a Retina display. Doubling the resolution by s=96 makes the image crisp.
