Ok - I admit to not being a computer expert, but I found a pretty cool screensaver.
The catch - you must do a wee bit of manipulation to get all of your wondrrful cobra shots in. The screensaver comes courtesy of Jag lovers (see link). After you download (~5 Meg), you simply transfer your cobra JPEG's and delete any of the Jaguar shots you don't like.
Check it out and let me know if there is any better Cobra screensaver out there. The beauty with this one is now my Cobra JPEG's are continuously displayed at random.
