Hi Yanghongmin,Greetings from Syncfusion.We have analyzed the reported issue “Image doesn’t appear when loading” and we found that the reported problem occurs due to stream is disposed once it consumed to display the preview.When loading the edited image, we will get the stream as below  





   
To resolve this problem, we have re-created the memory stream with existing stream bytes as per the code snippet.  





Device.BeginInvokeOnMainThread(()   =>  
            {  
                var buffer = new byte[16 * 1024];  
                byte[] byteArray;  
                using (MemoryStream ms = new MemoryStream())  
                {  
                    int read;  
                    while ((read = stream.Read(buffer, 0, buffer.Length)) > 0)  
                    {  
                        ms.Write(buffer, 0, read);  
                    }  
                    byteArray = ms.ToArray();  
                }  
                Imagebox.Source = ImageSource.FromStream(() => new MemoryStream(byteArray));  
            });
