If an item has attached documents - image of the item, in case it is a BOM - a list of the materials, etc, when the item is chosen on a Purchase/Sales orders line and wanting to send email confirmation or invoice for the order, it would be of great use to be able to choose these images or documents by having them available in "Add attachments from source" when sending the email.

You can still add them manually from the local machine, which however when having hundreds of items could be quite time-consuming.
