How to stop downloading signature attachments?

[yahtzee]

I want to download attachments in my email so that I can view them on the fly but when i look in my pictures folders I am seeing every single logo that has ever been in emails that have been sent to me in there....(1000+)....they are company logos, twitter/facebook logos from email signatures, etc...

How do make that stop?

Surely, I can't be the only one this has happened too.....anyone else?
