Hello,

I would like to add images to a Umbraco backoffice form.

I have a nested content document type and would like to alter html on the "Create new" form when creating a nested content node. Instead of showing the icon and document type title, I would like to display a big image (not custom icon but a different HTML.) see image attached.

So, I'm wondering if it's possible at all to alter the backoffice HTML without modifying the Umbraco core.

Thank you.
