    <p>You can BASE64 encode the content of the image directly into the SRC attribute, however, I believe only Firefox will parse this back into an image.</p> <p>What I typically do is a create a very lightweight HTTPHandler to serve the images:</p> <pre><code>using System; using System.Web; namespace Example { public class GetImage : IHttpHandler { public void ProcessRequest(HttpContext context) { if (context.Request.QueryString("id") != null) { Blob = GetBlobFromDataBase(id); context.Response.Clear(); context.Response.ContentType = "image/pjpeg"; context.Response.BinaryWrite(Blob); context.Response.End(); } } public bool IsReusable { get { return false; } } } } </code></pre> <p>You can reference this directly in your img tag:</p> <pre><code>&lt;img src="GetImage.ashx?id=111"/&gt; </code></pre> <p>Or, you could even create a server control that does it for you:</p> <pre><code>using System; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace Example.WebControl { [ToolboxData("&lt;{0}:DatabaseImage runat=server&gt;&lt;/{0}:DatabaseImage&gt;")] public class DatabaseImage : Control { public int DatabaseId { get { if (ViewState["DatabaseId" + this.ID] == null) return 0; else return ViewState["DataBaseId"]; } set { ViewState["DatabaseId" + this.ID] = value; } } protected override void RenderContents(HtmlTextWriter output) { output.Write("&lt;img src='getImage.ashx?id=" + this.DatabaseId + "'/&gt;"); base.RenderContents(output); } } } </code></pre> <p>This could be used like</p> <pre><code>&lt;cc:DatabaseImage id="db1" DatabaseId="123" runat="server/&gt; </code></pre> <p>And of course, you could set the databaseId in the codebehind as needed.</p>

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).
