Swimlane Email Plugin

I am using Swimlane Email Plugin for email notifications.
I take relevant data from application record such as email address, name and some other fields.
I was wandering if there is any way to add signature, logo and images to the email.

I’ve tried to use the html body but didn’t managed to.

Thanks Shamen

Have you looked at this

Or are you trying to send it from an Action?

That option is for Swimlane’s system emails and not workflow.
I’m using the following plugin : AppHub

I’ve found out that if I’m using triple quotes (""") I can insert base64 in the html context with no issues.
