Radimagegallery and maxjsonlength

[Thami]

Hi

Is it possible to change the maxjsonlength used by the jsonserializer in radimagegallery?? 

I sometimes need to load images temporarily by passing base64 string instead of url, but I get maxjsonlength error. 

I have tried in web.config but that doesn't help. 

Thank you for your help
