Developers have taken various tacks to enable progress reporting, for example
in some cases XHR can be used to download image files. Max Vujovic just
published a blog about the practicalities of doing so:
http://blogs.adobe.com/openweb/2012/01/13/html5-image-progress-events/. We
think it would be preferable to provide support for image progress events
directly.
I think this would be extremely useful. It would require a proposal to
W3C or WHATWG though.
Seems like this would need to follow CORS.
Even disclosing the file size is going too far for cross-domain without
CORS.
