Thunderbird is randomly replacing images I have inserted in my emails. The first screenshot is the email as I intended and sent. The second screenshot is the same email as received at the Recipients. The second image has been replaced and I am constantly getting queried by clients. The second image is from a footer from an email received in my Inbox. This happens randomly but often and with other images (also usually from old email sent TO me) Unfortunately it looks very unprofessional and I will have to use another Mail browser if I cannot find a solution. Thanks in advance for any help. Cheers Wayne
