Thank you for contacting Syncfusion support.
We have analyzed on the feasibility of the reported requirement and we can achieve your requirement “to use a custom image preview option” as a custom sample by overriding the default behavior of File explorer. Based on the complexity of this requirement, we will need 8 more business days, so we will update you with the custom sample within 8 business days.
We appreciate your patience until then.
