I want to replace company logo and address information from invoice report by an image. I created a module for that purpose.

Inherit View:

    <?xml version="1.0" encoding="utf-8"?>
    <odoo>
        <data>
            <template id="external_layout_header_inherit" inherit_id="report.external_layout_header">
                <xpath expr="//div[@class='header']" position="replace">
                    <div class="header">
                        <div class="row">
                            <div class="col-xs-12">
                                <img src="/report/static/src/img/my_company_logo.png" width="100%"/>
                            </div>
                        </div>
                    </div>
                </xpath>
            </template>
        </data>
    </odoo>
