Hi Lokelse,
Thank you for your interest in SYncfusion products.
I am able to reproduce the issue. This is due to the image is not converted to bytes properly. Please refer the below code snippet to do so:
[C#]
FileStream fs = new FileStream(@"..\..\Nature.jpg",FileMode.Open);
byte[] inByte = new byte[fs.Length];
fs.Read(inByte, 0, inByte.Length);
dr2["Photo1"] = inByte;
dr2["Photo2"] = inByte;
Here is the sample for your reference:
