The HTML5 Viewer and the legacy ASP.NET controls (PageView, ThumbnailView, and ImGearThumbnailList) need to be configured in your web application. The configuration settings apply to your application's web.config file. All legacy PageView and ThumbnailView controls in your entire web application will share these settings. Therefore, you cannot have separate settings for individual controls. In other words, these settings are web application specific.

The following is the list of configurations:

• Web Services Registration (Required)
• Image Data Provider Configuration (Required)
• Image Data Processor Configuration (Required)
• [Legacy] Server-side PageView and ThumbnailView control Error Logging Configuration Settings (Optional)

There are two ways to configure these settings:

• Edit the configuration settings within web.config. See the Description of Configuration Settings section for a description of required and optional settings to display images.
• [Legacy] Utilize "Smart Tags" or "Action Lists" visible in the design view in Visual Studio 2008, 2010, and 2012. These Action Lists will invoke a configuration dialog that will assist you in configuring the various settings required for your application.
