Constrain what files you can see with angularjs ng-flow -

-

i'm trying implement flow file uploader can't see how make user can select image files. copied example have

<div     data-flow-files-submitted="$flow.upload()"     flow-file-added="!!{png:1,gif:1,jpg:1,jpeg:1}[$file.getextension()]"     name="introduction-picture-upload">

but still see files available in upload window, not images. appreciated - thanks!

seems it's

<button     flow-btn     flow-attrs="{accept:'image/*'}">

not documented !
