Hi Issam,  
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.

Hi Issam, 

Thank you for being patient. 

We have prepared the sample to use the custom image preview option in FileExplorer and the sample can be downloaded from the below location. 

In the provided sample, we have used Pdfium to convert the pdf document into image and also overrided the in-built FileExplorer functionalities to use the custom image preview option in FileExplorer. 

Regarding your Query about  i would also want to make teh thumb size bigger , 

We have provided the e-thumbImage class for corresponding Image tag. You can use this class to customize the Images in your application. 

Please let us know if you have any concerns.
