We have an email app that sometimes needs to send pics (surprise)

When composing a message it has the option to attach a pic. Selecting this brings up a selection of Gallery and a couple of others.  So of course one can fire up the camera app, save the pic then pick it out of Gallery.

In one iteration of our system we could also get it to bring up "camera" as the picture source. Not sure what happened to make that go away. That of course was great - select "camera" as the picture source, point and shoot, job done.

Any ideas what I have to do to make this happen? Is this a website setting or an OS setting?
