By default, double clicking an image will open it in a program called ShowImage. As with all other Zeta applications, ShowImage is very light weight. It's just an image viewer, not an editor. It has the option to go into full screen mode and it is capable of doing slide shows. ShowImage also has zooming options to make sure the image will be scaled down to fit within the confines of the window. And if you resize the window, the image is automatically resized to fit (that is such a basic concept, but I can't tell you how many image viewing programs don't do that. Or at least, they don't do it well).
Zeta comes with a few basic servers such as ftp, telnet, and ssh. These are disabled by default (which is a good thing). They can be enabled by going to the network preferences, editing the profile for a given network device, and then selecting the services tab. At present though, these services seem to be intended to only ever be used by the owner of the system (i.e. yourself). You can only set 1 username and password for the entire services list. You can't setup multiple accounts. You can't even set up a different account for ftp and ssh! They aren't totally useless though by any means. It is certainly nice to be able to securely copy files to/from your own machine when you are at a remote location. Zeta comes with OpenSSH. The other servers include finger, ftp, netperf, qotd, and telnet. I would just forget those even exist. They are just going to open your system up to potential hacking.
Zeta also comes with an obscurely named program called PoorMan. PoorMan is a basic http server. It's not found in the same location as the other servers. It's located under Zeta -> Software -> Network -> PoorMan. It's not an extremely capable http server, but it is very simple to use. I certainly wouldn't recommend anyone use it on a publicly accessible network such as the Internet though. But if you are on a trusted local area network and you want to host a few HTML pages, PoorMan would get the job done (or if you are behind a firewall and you only allowed access to the server from known IP addresses).
I was disappointed, and a bit surprised, to find that Zeta is a single user operating system (but let me mention right up front that Zeta 1.5 will be multi-user). But at present, anyone that sits down at the system has full administrative access ("root" access). Running with full administrative access to the system all the time is a really bad idea. Microsoft has taught us that. I was surprised to see that a commercial operating system under active development in modern times wouldn't be more security minded. In 1986, it was understandable. In 2006, it's not.
Peripherals
When I plugged my 64MB USB thumbdrive into the computer with Zeta up and running, nothing happened. I didn't get an icon on the desktop. At first, I thought I had disabled automatic mounting. If you right click on the desktop, and go to mount, and then choose settings, there are a few different options for mounting. Including the ability to disable the automatic mounting of devices.
But when I checked the mount settings, automount was enabled. So I then went to the preferences panel and brought up the USB tab. From there, I could see that Zeta did recognize my USB thumbdrive, but I had no options to mount it. I closed down the Preferences and then went to Zeta -> Preferences -> Drive Setup (it's weird that all other preferences can be accessed from the preferences panel. However, drive setup and e-mail can only be accessed from the preferences menu hierarchy. I wonder what is up with that?). From the drive setup utility, I could see that Zeta knew my thumbdrive was formatted as Ext2, and I was able to mount it.
