Hi all, I'm trying to put image (client signature) inside pdf quote builder but without luck. Did anybody know the trick how to do this?  I made this simple extension to enrich PDF with values. If I use form field in PDF I see base64 string. If I use image tag it will remains empty. 

from odoo import models


class IrActionsReport(models.Model):
    _inherit = 'ir.actions.report'

    def _get_form_fields_mapping(self, order, doc_line_id_mapping=None):
        result = super()._get_form_fields_mapping(order, doc_line_id_mapping=doc_line_id_mapping)
        result.update({
            'signed_on': order.signed_on,
            'date_order': order.date_order,
            'customer_signature': order.signature,
            'user_signature': order.user_id.sign_signature,
        })

        return result
