Isn't that part of the point? This is a totally normal thing to want, but no it is forbidden. Could a third party developer fix it? They could on Android.
They could, but it's strictly speaking not needed. It's already solved/fixed.
Just enable/install Google+/Picasa sync and you have all your pictures on all your Android-devices, and on the web, just in case you need it outside this semi-closed Google system.
