ImageList class provides methods to load, store, and retrieving images from local file paths or URLs. It maintains an internal dictionary (images) that associates each image with a unique name, allowing efficient access to the stored images.
ImageList.LoadImage(fileNameOrUrl)- Loads an image from a file path or a URL.
- The name of the image, which can be used to reference the loaded image in other methods, or an empty string if the image could not be loaded.
ImageList.GetWidthOfImage(imageName)- Retrieves the width of the stored image in pixels.
ImageList.GetHeightOfImage(imageName)- Retrieves the height of the stored image in pixels.
