That sounds right, but I can't get it to work.
To be clear, I want a logo on this page … it's the generic server WHM webmail emtrance, not any particular cpanel account.
The cpanel accounts all use Jupiter if that makes a difference. But this login takes you directly to a webmail interface (Horde or RoundCube). These users don't even have cpanel access.

I believe the logo will only be displayed once the client logs in in but hopefully @cPanelAnthony could clarify this for us 
The details outlined by @andrew.n will only work for logos inside the cPanel interface, and not the main Webmail logo at hostname.com:2096
