ASP.NET How to display a constantly changing picture without flickering?

Question

SQL

There is a table with pictures in the MSSQL database. The table is updated every second. I am displaying a table using WebForms and updating it with a timer. The only problem is that the picture flickers when updating. In the table, the code that displays the image is as follows

where Handler.ashx reads the image by id from the base, as an array of bytes, and
sends it as follows
context.Response.BinaryWrite(image);
reader.Close();
connection.Close();
