Season's greetings and Happy New Year 2018 to All.

We are trying to create rule with Auto-reply to all emails with a picture file that is sent with picture in the body of an email.
If i create rule with auto-reply and include the picture file in the rule, then the file is sent as an attachment. We want the email to be sent with picture file in the body of the email and not as an attachment.
I created a new signature and attached the picture file in the signature. This works perfectly when i compose or reply to email directly. But when i create auto-reply rule it sends email without the signature.
Can someone guide if it is possible to send auto-reply with email signature included ?

Thanks in advance.
