@fastidious On the loss of quality on image processing / resizing… I think it might have something to do with the resampling that occurs during the resize operation. On the backend yarnd we use the gift library for most processing (mostly just Resize() and ResizetoFit()). PNG itself is a lossless image format with selectable compression levels depending on output size and decode speed, so I think the culprit is the resampling…

@prologic I will run a small research to see what’s would the best resampling be. I will be looking something of a compromise, whilst trying to achieve better quality.

@prologic so I checked. It seems we are already using the best resampling method. So… hmm, yeah. Other than resizing the images less—say, instead of 850px, resize to 1000px, if bigger than 1000px—I don’t see any other way to get better results.

@prologic this is easy to test. I will pull one original, host it, and link it on a twt. Then we will compare it to the uploaded version. Granted, it will be a visual comparison only.
