You can add a button that provides a convenient way of sending pictures to people by email.
To do this, click Edit ▸ Preferences and go to the Plugins tab. Then, check Send By Mail and click Close. This will give you a Tools ▸ Send by mail menu item.
In order to enable this feature, you need to have installed eog-plugins.
Evolution mail must be set up to connect to your email account for this to work.
