One of the greatest features of Usenet is the ability to look at and download a myriad of pictures and images on about any and every possible topic you can think of. You can find a variety of professional pictures as well as many personal image collections that some users have decided to share with the rest of the Usenet community.
There are images ranging from old-fashioned cars to shots of nature and animals – you can literally find anything you need. Usenet pictures are usually located in the binary newsgroups as that is where all articles with attachments are supposed to be posted. You can probably find a small number of pictures in text newsgroups, but those would have probably been posted there by mistake, as it is not recommended to post binaries in text-only newsgroups.
Certain Usenet Service Providers, such as FastUsenet.org, make it very easy for their users to browse though the millions of pictures posted in Usenet and select only the ones they want for download. FastUsenet.org provides a thumbnailing interface for their customers, where users can preview thumbnails of the images before actually downloading them, thus saving them a lot of time and bandwidth (which translates into money eventually).
This way users can browse through all the picture newsgroups they wish and preview all the images they contain, without worrying about using up or exceeding their download limits, while getting unwanted content. There are also software packages which let users extract only pictures out of binary groups, containing all other kinds of binaries (attachments). Some of those could be automated, or set to download every Usenet picture they encounter in a certain newsgroup, or on a certain server. That feature is beneficial if you want to download all the images this group contains, without previously making a selection.
