Logo image being sent

I have edited the simple responsive template as I don’t want a logo included in some of my mail outs. When I send a campaign, however, the logo image file, whilst not included as part of the body of the mail out (I have removed the [LOGO] text), is included as an attachment - almost an orphaned attachment.

Is there anyway to stop the logo image being sent as an attachment?

I came here to ask the same question. There is an attachment when I view the email in Gmail. When I download an email via Thunderbird, there is no attachment - until I change the format to Plain Text, . in which case it and the phpList logo appear as attachments. So my guess is it’s something to do with the plain text version sent by phpList. But I have no idea how to get rid of it.
