How do I delete pictures that I opened with email to delete....?

When I open emails and it has a picture in the email that downloads, how do I delete these pictures even though the email is long deleted. and why does it save every picture? Can this be slowing me down?

I had this same problem - when your in your email on the left hand side look for search short cuts - click my attachments - at the topp of that page click message view - from there you can check mark the mesages and delete from there -
