Free images are available all over the Internet, and one great resource is images found on the various Internet newsgroups. ALLPicturez is a program that searches through Internet newsgroup postings, finding pictures for you to download.
Using ALLpicturez, when you log onto a news server, it automatically displays a list of only the newsgroups that contain pictures, and it filters out everything from the individual newsgroups except for the pictures for you to download. It has a very simple interface that displays small thumbnail images of the pictures it finds. You then click on to download the full size images.
