I know this was requested in the past (8 years ago)
However i’m just updating a request to add a product image when adding a product.
This could be attached the same way as IP attaches “Attachments +Add files” to pre populate this area if the product is added to an invoice (and remove the attachment if the product is removed) from the quote or invoice.
Also the ability to upload the image when creating a product and possibly rename the product picture as the product name or sku so it is clear to the customer what it relates to in the invoice.
This way if you add a product to a quote or invoice there is a reference for the customer to check when emailed. It also saves us from having to up load an image every quote.
Hoper this is clear.
