In a recent project utilizing the wonderful Pipeline theme (v4.5.1) by Groupthought, I came upon a strange issue where certain images were not displaying correctly. Interestingly, on desktop, at various breakpoints, the images would show up without issue. But on an actual mobile device, certain images would display and then partially disappear. This would happen both on Safari and Chrome on iOS.
During the process of debugging, I thought it'd be useful to confirm that the images were not damaged in some way and happened upon some particularly useful tools.
