I wouldn’t say it solves a problem per se, but I think it would make it easier for people to share wireframe/clay/final render comparisons. A lot of the time, people make those comparisons using image editing software- this way is both faster and interactive. For example:
This image surely would work better as an interactive slider, wouldn’t you say @Icaro_Carvalho ?
Also this one: Suspect (duck) would it have been useful to be able to make an image comparison slider instead of making it in image editing software, @Erf ?
It could also be used for raw/processed images like this: Key (Stray Inspired) @ClarkKhant
As said, even if something breaks, it just displays the images normally, so it’s low-risk, and I’m very active with bug fixes
