Lightning PictureBox Pro is a picture container which loads and scales pictures of any size into its displaying area with visual feedback and make them automatically scrollable if the user moves the mouse pointer over content (in case the pictures do not completely fit into it). The component is very useful if you have limited space in your application to load and display external images in a comfortable and efficient way. There are various modes for scaling the picture content and the images can be loaded and unloaded dynamically at runtime. The component has inbuilt pre-loaders to indicate downloading progress and some extra features for customizing its appearance and behavior (see parameter description).
