This is a Jetpack integration issue. For some reason, the request we send to the external media API no longer works with Jetpack sites, the Jetpack client can't determine the file type of the image and rejects the upload request. FWIW, this worked when we first rolled out Pexels, so I'll carry on looking at this to determine what's changed and see how it can be fixed.

Also does not work in the WordPress.com/media, after you click "copy to media library":

The problem here is that uploaded images are getting a .tmp extension, which Jetpack doesn't recognise as an image. I'm working on this today, although I'm not sure how easy a fix will be. I'll keep things updated here, it doesn't seem to be a Jetpack or Calypso issue though, but I guess this is where peeps will check for issues :)

Fix has been deployed, images are copying correctly to Jetpack powered sites again.
