WMS App - Add photos when picking or packing an order

Once an order is picked, our warehouse staff take photos for proof that all items are included in the order. The second photo taken is once packed to show the size and condition of the finished parcel (and what the customer should expect to see). This would be very helpful if there was a quick way to add this to the attachments tab in the Sales section direct from the app as we take the photos on a dedicated phone camera (iphone).
