Imgur is financed by advertising, and they offer pro accounts, admittedly subscribed by a sliver of users only. Revenue per user are orders of magnitude lower than for a for-pay service, but they have far more users. Their servers (and costs) are optimised to serve a limited amount of photo fast, host a little more and serve them not so fast; they most likely have far less photos, at far lower resolutions, than Everpix who hosts entire shooting sets for pro-am photographers.
