I am planning to start allowing images on my birdlist, but I want to use one format, JPEG, only. The manual (1.8d which we are still using) refers to Attachment= images, but what I would like to use is Attachment=.jpg instead. Will Listserv allow this more extreme limitation and exclude all other image formats? Is there anything I should watch out for? Thanks in advance, Barbara Passmore [log in to unmask]
