I wonder if Alamy are accepting video again. I'm currently about to sign in on their site and I see some video footage being displayed (something Ive never seen before on their start up page.) And there is some text that says: "License your photos, illustrations and videos to the world's leading brands."
In last several years Alamy has dropped the hint in their own contributor Forums that they would be opening video submissions to their contributors. Has never happened as far as I know.
For sure, they've teased things which never came to pass.
Having their phone upload stockimo, now gone, android compatible was another.
Though IIRC phone submissions are now acceptable to Alamy under certain circumstances, but I haven't looked into it, certainly some Live News submissions.
