What is a way of having a button/item which changes its image? It needs to work with customisation. It is a button that is like a checked/ unchecked except its image changes instead of its checked state. therefore it also needs to update based on some internal variable.
Is there a simple way of doing this?

In the case of non-customizable toolbars and menus, you should use the command manager (the CExtCmdManager::CmdSetIcon() method). Otherwise, the command manager keeps the original version of command’s icon. Each toolbar button and menu item is described by the corresponding instance of the CExtCustomizeCmdTreeNode, which stores a customized version of the icon because the user can change/edit the icon when the Customize dialog is open. The customized version of icon is stored in the CExtCustomizeCmdTreeNode::m_iconCustomized property. Its protected in 2.82 but public in 2.83 and will be public in latter versions. So, you should mark it as public.
