I think you’re on to something. If I open the email in a web browser, it looks just fine. But then if I right click an image and try to open it on it’s own, I get this error…
403 – Forbidden Error

Common reasons for this error are:
Incorrect file/directory permissions: Below 644.
In order files to be read by the webserver, their permissions have to be equal or above 644. You can update file permissions with a FTP client or through cPanel’s File Manager.
Restrictive Apache directives inside .htaccess file.
There are two Apache directives which can cause this error – ‘Deny from’ and ‘Options -Indexes’.
