Express NewsPictures is a powerful newsreader specifically designed for downloading and viewing pictures and other binaries (audio, video and more) from newsgroups. The program downloads articles with binaries inside, decodes them and saves on your hard drive. It filters spam, leaving only those articles that contain real binaries. The program lets you preview the downloaded pictures and shrink or scroll the picture if it doesn't fit in the preview window.
