Hi David,

I am not entirely sure if what you want to achieve is possible and I think that is more to do with the structure of the blocks, so I just wanted to confirm the content setup.

Content Setup:

----Page > Content Area > Single Block Content Area > Rich Text Editor Block (Anti-Pattern - Nested Blocks)

If this is correct then as I presume it will be difficult to achieve your desired outcome as the solution needs to be context aware to know when to add the images tool to the toolbar.

If this is not the case then you possibly might be able to achieve this with 'SettingsTransform', with the following content setup:

----Page > Content Area > Rich Text Editor Block

Thanks

Paul
