Hello Angela,

The WebImageViewer exposes an Items collection that can be populated with ImageItem objects (a single object represents a single image). We can manually create these objects by passing the relative image path in their constructor. We can do this for all images from a specific folder by using the built-in .NET API.

For example:

protected void Page_Load(object sender, EventArgs e)
{
PopulateImageViewer();
}

private string[] GetFiles()
{ 
string webCurrentDirectory = HttpRuntime.AppDomainAppPath;
string[] filePaths = Directory.GetFiles(webCurrentDirectory + @"\images\", "*.jpg", SearchOption.TopDirectoryOnly);
string[] fileNames = filePaths.Select(filePath => Path.GetFileName(filePath)).ToArray();
return fileNames;
}

private void PopulateImageViewer()
{
string[] fileNames = GetFiles();

foreach (string fileName in fileNames)
{
ImageItem imageItem = new ImageItem(@"images/" + fileName, fileName, fileName + " tooltip");
imageViewer.Items.Add(imageItem);
}
}

Please note that the above code is just a single approach that can be used and in order to work with extensions other than .jpg, we can simply use the Directory.GetFiles method again by changing the searchPattern argument.

I have attached a sample application that demonstrates the mentioned approach.

If you have any questions, please let me know.
