audiopreview is a command-line tool that plays previews of many audio file types (Ogg, MP3, etc.), video file types (AVI, MPEG, Real, etc.), and Internet streams. It can also be used as a regular command-line media file player (i.e. play the files entirely like yauap or mpc123 would).
Image Selector previews images defined in select input options. It can take as a parameter the identifier of a form select input element which has options set to the URLs of images to be picked by the user. The object can display the currently-selected image inside a preview page element. The object can also change the currently-selected image to move to the next, previous, first, last, or to any of the images in the list.
