Hi,

you can add an inline-Image:

<img src="data:image/png;base64,${object.company_id.logo}" style="width: 250px;" />

But as the inline-Image gets removed by html-cleaner, you will have to use the following patch:

     # some corner cases make the parser crash (such as <SCRIPT/XSS SRC=\"\"></SCRIPT> in test_mail)

         cleaned = cleaner.clean_html(src)
     except TypeError, e:

Hope this helps.

Best regards,

You can add attribute sanitize=False to signature field at openerp/addons/base/res/res_users.py file

 'signature': fields.html('Signature', sanitize=False)

Unfortunally not all email clients shows base64 encoded images. Such images should be replaces by attachments. You can overwrite build_email function of a ir.mail_server model:

class ir_mail_server(models Mode): 
    _inherit = "ir.mail_server"

    def build_email(self, email_from, email_to, subject, body, email_cc=None, email_bcc=None, reply_to=False,
               attachments=None, message_id=None, references=None, object_id=False, subtype='plain', headers=None,
               body_alternative=None, subtype_alternative='plain'):
        """ copy-pasted from openerp/addons/base/ir/ir_mail_server.py::build_email """

        ftemplate = '__image-%s__'
        fcounter = 0
        attachments = attachments or []

        pattern = re.compile(r'"data:image/png;base64,[^"]*"')
        pos = 0
        new_body = ''
        while True:
            match = pattern.search(body, pos)
            if not match:
                break
            s = match.start()
            e = match.end()
            data = body[s+len('"data:image/png;base64,'):e-1]
            new_body += body[pos:s]

            fname = ftemplate % fcounter
            fcounter += 1
            attachments.append( (fname, base64.b64decode(data)) )

            new_body += '"cid:%s"' % fname
            pos = e

        new_body += body[pos:]
        body = new_body

        //...

Or you can just try my module res_users_signature which also add signature templates feature.
