Align image on tumblr page & add link

C'est ce qu'une entreprise en/au(x) Australia recherchait pour leur web design

I have a tumblr page that I have designed myself. It is completely blank with only one jpg on it.

I need that jpg centre aligned, and connected to an email address so that when you click on the jpg, it opens the email client.

The web page is a holding page for a future website.

I am also open to using a different host if it is easier to do so. Voir plus
