Email attachments

Well, my Comcast Email doesn't time out although it is extremely slow to connect to my account. There are other problems though. First, I almost never get a notification when I have new email. Tonight I had 3 new email messages but the email icon showed nothing new. Second, most of my email comes with pictures or links. Most of the time the pictures do not show. Links are almost always not clickable. If I right click on the picture icon or the link and select "open in new tab" it will then open in the new tab. These problems have been ongoing for several years. Callin Comcast Support is a waste of time since they never have any answers. They try to tell me it's my fault. Oh, Hotmail, Yahoo mailand GMail work fine on this computer.
