You saved the attachments from the email to My Pictures did you?
When you say icons, do you mean the thumbnail images are not blurred in My Pictures?
Hover the mouse pointer over the thumbnails in My Pictures, what are the dimensions of the pictures 300X400 etc and the size in Kb's, and did they view larger and not blurred when in your email program?
Just wondering if they were sent as small pictures in the first place, in which case enlarging them will just make them blurry. If that were the case maybe they could they be re-sent in a larger size?
