There are several ways to send an invitiation.

You can customize the invitation for your meeting by editing your existing meeting,  clicking on the Advanced Options button -- (lower left hand side of screen) and then selecting the Send Invitations tab. You cannot include pictures but you can add text into the invitation. Be careful when modifying the custom invitation to not delete text that contains meeting variables in "{  brackets}" or you will possibly remove important information.
