Comment 5 for bug 1549156

After digging up a bit more, even with Ken's MP share-data as a feature with plain http URIs is currently not working at all because of various issues (not related to webapps):

- webapps do not deal with the downloading part of the job, nor do they really rely on the image to be local, they rely instead on the toDataURI function of the ContentItem being handed to them during the transfer:

this function does not deal with non local URIs,

- unity8 by default treats all share-data for scopes previews with a URI not starting with file:// (e.g. not local), as an external one, and overrides the content-type to 'Links' instead of pictures,
