I'm in locahost user and I've tried to launch my first mass mailing campaign.

Im under  Odoo 10.0-20170715 community edition and run under Win 10

The issues I got is that when I draft the mailing all is ok but when I send as test courriel on different emails box for try (Yahoo, Gmail...) instead pics I get some broken pics preview.

I've tried many way to host my pics: by direct import in Odoo, in my google drive or  web server but nothing works

Email entrance and exit are  setted with Smtp Gmail

Excepted pics all text, order forms link are well recepted and work great in the test email

I think the problem come from that Im under localhost but I cant manage to find solution by my self to be honnest.

 Thanks in advance for your help
