robpoole,
Thanks for getting in touch! I’m assuming you’re talking about displaying logos in the WYSIWYG editor for the Event Description? If so, then you should be able to install some kind of table plugin to create columns in the editor. Something like this plugin might do the trick, but keep in mind that we can’t officially support third-party plugins if they cause conflicts with The Events Calendar.
Hopefully that gets you started on the right track. Good luck and thanks! 🙂
