    <p>The 'Parameter is not valid' error is occurring because the byte array you've fetched back from the database does not represent valid image binary data.</p> <p>There are various reasons this might happen. As a start, take a look at the data in your database - it might not be storing the binary data you expect.</p> <p>In the meantime, I've quickly thrown together a small console app that does what you're after:</p> <pre><code>class LoadImageFromDbSpike { private const string ConnectionString = @"Data Source=[SERVERNAME];Initial Catalog=[DBNAME];Trusted_Connection=true;Connect Timeout=180;"; private const string ImageOnDiskPath = @"c:\test.png"; private const string OutputPath = @"c:\output.png"; static void Main(string[] args) { var imageData = File.ReadAllBytes(ImageOnDiskPath); var imageId = StoreImageData(imageData); var imageDataFromDb = LoadImageData(imageId); File.WriteAllBytes(OutputPath, imageDataFromDb); } private static int StoreImageData(IEnumerable&lt;byte&gt; imageData) { const string insertCommand = "INSERT INTO ImageSpike (Image) " + "VALUES (@ImageData); " + "SELECT SCOPE_IDENTITY();"; using (var con = new SqlConnection(ConnectionString)) using (var cmd = new SqlCommand(insertCommand, con)) { cmd.Parameters.AddWithValue("@ImageData", imageData); cmd.Connection.Open(); return (int) (decimal) cmd.ExecuteScalar(); } } private static byte[] LoadImageData(int id) { const string loadImageCommand = "SELECT TOP 1 Image FROM ImageSpike " + "WHERE Id = @Id; "; using (var con = new SqlConnection(ConnectionString)) using (var cmd = new SqlCommand(loadImageCommand, con)) { cmd.Parameters.AddWithValue("@Id", id); cmd.Connection.Open(); var result = cmd.ExecuteScalar(); return (byte[]) result; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
