    <p>When my images are being loaded from my database on my web server, I see the following error:</p> <blockquote> <p>A generic error occurred in GDI+. at System.Drawing.Image.Save(Stream stream, ImageCodecInfo encoder, EncoderParameters encoderParams) at System.Drawing.Image.Save(Stream stream, ImageFormat format) at MyWeb.Helpers.ImageHandler.ProcessRequest(HttpContext context)</p> </blockquote> <p>All my code is attempting to do is load the image, can anybody take a look and let me know what I'm doing wrong?</p> <p>Note - This works if I test it on my local machine, but not when I deploy it to my web server.</p> <pre><code>public void ProcessRequest(HttpContext context) { context.Response.Clear(); if (!String.IsNullOrEmpty(context.Request.QueryString["imageid"])) { int imageID = Convert.ToInt32(context.Request.QueryString["imageid"]); int isThumbnail = Convert.ToInt32(context.Request.QueryString["thumbnail"]); // Retrieve this image from the database Image image = GetImage(imageID); // Make it a thumbmail if requested if (isThumbnail == 1) { Image.GetThumbnailImageAbort myCallback = new Image.GetThumbnailImageAbort(ThumbnailCallback); image = image.GetThumbnailImage(200, 200, myCallback, IntPtr.Zero); } context.Response.ContentType = "image/png"; // Save the image to the OutputStream image.Save(context.Response.OutputStream, ImageFormat.Png); } else { context.Response.ContentType = "text/html"; context.Response.Write("&lt;p&gt;Error: Image ID is not valid - image may have been deleted from the database.&lt;/p&gt;"); } } </code></pre> <p>The error occurs on the line:</p> <blockquote> <p>image.Save(context.Response.OutputStream, ImageFormat.Png);</p> </blockquote> <p><strong>UPDATE</strong></p> <p>I've changed my code to this, bit the issue still happens:</p> <pre><code>var db = new MyWebEntities(); var screenshotData = (from screenshots in db.screenshots where screenshots.id == imageID select new ImageModel { ID = screenshots.id, Language = screenshots.language, ScreenshotByte = screenshots.screen_shot, ProjectID = screenshots.projects_ID }); foreach (ImageModel info in screenshotData) { using (MemoryStream ms = new MemoryStream(info.ScreenshotByte)) { Image image = Image.FromStream(ms); // Make it a thumbmail if requested if (isThumbnail == 1) { Image.GetThumbnailImageAbort myCallback = new Image.GetThumbnailImageAbort(ThumbnailCallback); image = image.GetThumbnailImage(200, 200, myCallback, IntPtr.Zero); } context.Response.ContentType = "image/png"; // Save the image to the OutputStream image.Save(context.Response.OutputStream, ImageFormat.Png); } } </code></pre> <p>Thanks.</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.
