"I'd say that there is evidence that the victim has been killed by a human, has not committed suicide, that only one other person is alive in the house, and that no human has entered or left the house during the entire process. Oh, and the knife in the victim's back also has the alive man's fingerprints on it. And he's stabbing the corpse every time you blink while refreshing the page." -- WindPowa
As for the webhost, the execution and request stuffs are fast (below 1 second) and the number of images listed should not impact that. However, the download to user / upload from server speed is limited 250KB/s or lower (lowest limited to 90 KB/s) from the site host itself. Since the images I host there usually are about 600 KB to 1 MB++ size, it slows in loading though.
