#Remarks
The CustomImageProcessing event occurs only when the ImageGallery extension is bound to a folder or to binary data. The event is raised for each image three times (for a thumbnail, a fullscreen viewer image and a fullscreen viewer thumbnail), and enables you to custom process it. For instance, you can handle this event to add a watermark.
The event parameter’s properties allow you to access the processed image (ImageGalleryCustomImageProcessingEventArgs.Image) and to identify the processed image location within the gallery (ImageGalleryCustomImageProcessingEventArgs.ImageLocation). The ImageGalleryCustomImageProcessingEventArgs.Graphics property provides methods for drawing over the image.
