None that I know of, but it should be easy to build one, just combine TImage, TTimer, TDirectoryEdit (or other directory selection component). Set TDirectoryEdit's OnChange event to get all images from selected directory (use
FindAllFiles with specified mask, e.g. '*.jpg;*.bmp;*.png'). You can choose whether save the result in a global / form's private variable and load the image on TTimer's OnTimer using TImage.Picture.LoadFromFile or use a TImageList to preload all of the images (this is faster, but more complex code).
