+
+If the document contains external resources, such as images, GroupDocs.Viewer loads them when rendering a document. This allows the document to display correctly, but is a potential security risk.
+
+GroupDocs.Viewer allows you to manage loading of external resources contained by a document. These features are supported for the [Word Processing File Formats](https://docs.fileformat.com/word-processing/).
+
+Use the [LoadOptions](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.options/loadoptions) object to manage loading of external resources.
+
+## Skip loading of external resources
+
+The following code snippet shows how to deny loading of external resources:
+
+{{< tabs "example3">}}
+{{< tab "C#" >}}
+```csharp
+LoadOptions loadOptions = new LoadOptions();
+loadOptions.SkipExternalResources = true; // Skip loading of external resources
+
+using (Viewer viewer = new Viewer("business-flyer.docx", loadOptions))
+{
+    HtmlViewOptions viewOptions = 
+        HtmlViewOptions.ForEmbeddedResources();
+
+    viewer.View(viewOptions);
+}

+LoadOptions loadOptions = new LoadOptions();
+loadOptions.SkipExternalResources = true; // Skip loading of all external resources
+loadOptions.WhitelistedResources.Add("avatars.githubusercontent.com"); //Enable loading of external resources that has `avatars.githubusercontent.com` fragment in resource URL.

+## Set timeout for loading of external resources

+The default timeout is 30 seconds. GroupDocs.Viewer allows you to change this value.
+
+The following code snippet shows how to set a timeout to load external resources:

+{{< tabs "example1">}}
+{{< tab "C#" >}}

+## Render worksheet by page breaks and print area
+
+GroupDocs.Viewer uses page breaks to split a worksheet into separate pages. Microsoft Excel adds automatic page breaks based on paper size and page settings, but you can also insert manual horizontal and vertical page breaks. Switch to **Page Break Preview** in Microsoft Excel to see where page breaks appear on a worksheet.
+
+Also, you can designate one or more cell ranges in a worksheet as the only region to print (a _print area_). A worksheet can contain multiple print areas. Each print area prints on its own page.
+
+When printing, Microsoft Excel splits a worksheet into pages using both page breaks and print areas. In the following image the red line shows the print area, and the blue line shows page breaks:
+
+![Specify page breaks and a print area in Microsoft Excel](/viewer/net/images/rendering-basics/render-spreadsheets/page-breake-vs-print-area.png)
+
+GroupDocs.Viewer also supports this option. Call the [SpreadsheetOptions.ForRenderingPrintAreaAndPageBreaks](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.options/spreadsheetoptions/methods/forrenderingprintareaandpagebreaks) static method and assign the returned `SpreadsheetOptions` instance to the [ViewOptions.SpreadsheetOptions](https://reference.groupdocs.com/viewer/net/groupdocs.viewer.options/baseviewoptions/properties/spreadsheetoptions) property to display only the worksheet's print area in the output HTML, PDF, or image file.
+
+The following example renders the Microsoft Excel spreadsheet using page breaks and print areas displayed in the image above to PDF:
+
+{{< tabs "example4">}}
+{{< tab "C#" >}}
+```csharp
+using GroupDocs.Viewer;
+using GroupDocs.Viewer.Options;
+// ...
+
+//render spreadsheet to PDF
+using (var viewer = new Viewer("products.xlsx"))
+{
