I'm not sure if the machinery (CFNetwork, etc.) on OS X currently does this, or whether it uses the MIME type returned from the server combined with file extensions to determine the actual image type. 2170290 1 karlcow 2026-01-08 07:56:53 -0800 It seems to me this is now the case. Currently it uses the mime type. This needs tests to understand what is being asked exactly. And look at the behavior of all browsers.
