PictureBox.LoadAsync Method
.NET Framework 4
Loads the image asynchronously.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Besides calling the LoadAsync method, the WaitOnLoad property must be set to false to load an image asynchronously. When you load an image asynchronously, you can handle the LoadProgressChanged event to determine the progress of an image load or the LoadCompleted event to determine when an image load has completed.
