ES Emails Send Using Custom Logo

Hellooooooo,

Just a question about ES emails send. As you can see in attached picture, I have overwrited the "easysocial" logo by my own logo. But everytime I update ES to the latest version, the ES logo overwrite MY logo. NOT a probleme, but I can save my time if I don't need to re-upload everytime my logo located here :

My question: is there a way where I can to define / set my logo ?

Then, I currently CHMOD the logo by CHMOD 444, do you think it solve the probleme ?

Thanks for answer.

Don't think I don't love Stackideas... but... the registred members of my (futur) site will asked "what is Easysocial"

Love,

Best Regards,

Yann Anderson
