I'm getting an increasing number of emails - mainly from businesses I deal with - that display a large image with the subject line of the mail when it appears in the message pane. An example would be a music company I deal with has a picture of a guitar superimposed on the subject line. This makes the message pane cluttered and I find it annoying.. Is there any way to prevent these displaying or better still prevent them from being downloaded? TBird 52.9.1 (64 bit) on a Linux system Thanks.
