Hi Rahul,
Greetings from Syncfusion support.
Currently, we doesn’t have any API to fulfil your desired requirement. We consider “Provide removeUrl support on insertImageSettings API” as feature request from our end and it will be available in any of our upcoming releases.
Note: We will check and provide the workaround solution with sample on 12th December to meet your desired requirement.
Regards,
Pandiyaraj
