Serve Scaled Images

[Videx]

Of course, to achieve this you would have to scale the images as they come in, not as they're served. There are various mods that will do that, but what a pain. And as a user with a larger screen resolution, you can bet it would upset me to have to look at all your tiny images.

These days you should probably just forget about it and go with a caching service like Cloudflare.
