    It seems to be you are using OOP method of Database connection. I hope the following will resolve the issue.

    Replace

    $row['Picture_File']
    

    into

    $row->Picture_File
    

    Full line of code

    echo '<img src="data:image/png;base64,'.base64_encode($row->Picture_File).'">';
    

    NOTE:

    Make sure to change mime type near image/png; to respective. For example if jpg then change into image/jpeg; etc


    Tip

    While save image as blob into database, you may need to store mime type too.
