Pictures inside email content -> How to add them as attachments?

Hello! Sometimes my customers add pictures that are relevant to the deal inside the email content instead of adding them as attachments. This gives a headache when trying to find that one picture from one of 50 emails at the later stage.

Is there a way to add those pictures to "attachments section" so I can find them easily in case I need to get back to them? I know I can do that with regular attachments.

Regards
