I assume 99% of users are using downsampling, to get thumbnails.

CHROME ON MAC USERS: Use the imgur links instead of the 0x0 links, some users seem to be reporting crashes related to TLS. The downsampling also isn't that great. Original image: https://raw.githubusercontent.com/haasn/cms/master/rings_lg_orig.png https://raw.githubusercontent.com/haasn/cms/master/rings_lg_... Downsampled with imgix: http://chen.imgix.net/rings_lg_orig.png?w=400 http://chen.imgix.net/rings_lg_orig.png?w=400 Downsampled with imagemagick: https://0x0.st/1-.png https://0x0.st/1-.png http://i.imgur.com/Nvl7tAm.png http://i.imgur.com/Nvl7tAm.png Downsampled with imagemagick, gamma correct: https://0x0.st/1i.png https://0x0.st/1i.png http://i.imgur.com/Hrm4COb.png http://i.imgur.com/Hrm4COb.png Note how the luminance becomes square in the center (step back a bit if you can't see it), and also the edge pixels on the imgix version.

  Just FYI both of those 0x0.st images crash Chrome (Version 42.0.2311.135 (64-bit)) for me and several colleagues... You don't even have to click the link, just simply get Chrome to load it into memory edit: looks like something to do with Chrome's pre-fetching and https cert parsing, I think they're literally parsing the "0x0" string within the cert as a memory location

    Ironically enough, it looks like the crash only happens on OS X.

  Opening the 0x0.st image crashes Chrome on Mac. Just Googling 0x0.st causes whole browser to crash!

    What about this downsampler? I think it's a bit better http://res.cloudinary.com/rancloud2/image/fetch/w_400/https://raw.githubusercontent.com/haasn/cms/master/rings_lg_orig.png http://res.cloudinary.com/rancloud2/image/fetch/w_400/https:...

      That one looks extremely close to the imagemagick one, slightly less aliasing and slighly more blur - it's down to a matter of preference. Most importantly, it doesn't have the horrible box window that the imgix resampler has.

  Warning: clicking on the 3rd link in your comment repeatably crashes Chrome (the entire browser, not just the tab) for me.
