Sending an image in an email using sendgrid

I'm using the file resource input field to send an image to xano, which I then want to send in an email alongside a message (as an attachment or in the message body).[image.png]
1. Do I have to save it to the database to pass it into the email?
2. Is there a way to add it as an attachment?
3. If I can only add it to the body, how do I add it to the message? can it be 'pasted' in so it doesn't have to be saved or do I have to save it and then use the URL in an

tag in the message?

Thanks
