In my particular application, a user may capture a photo that will later be used in the Zoho app, when it's convenient  (but not necessarily while the user is actually running the app)  i.e. the user would have to go back and do the photo AGAIN, just to get it to the Zoho database.  And of course this is rarely possible to get the same photo twice, at separate times.

It is far too troublesome, to push the photo to some cloud service, then figure out the link address and type in the HUGE link address and hope they don't mis-type the address.  It would be so much simpler to simply select a photo already stored in the phone's photos location to get saved to the Zoho database once and for all.
