It is possible?

Send item image(photo data) and item data(feature data) to Minecraft PE?
Can I make a new item?

Items = Client
Plugins = Server
You cannot change the Client using the Server. For new Items, you can only use an already existing item and change the name and the usage. You cannot add completely new Items, for that, you need access to the Client: Mods.

You could use existing items but change the meta/damage on the item so you can easily identify them. The only other alternative is using NBT to add your data to things.

0.14 will include json mods, no?

Oh i can't make new items. Thank you.
i'll try to add data using nbt
