Go to Evangelo's page: http://www.eaprogramming.com/
and download the zip file for memory cards. Take a USB flash drive, load the 20 slides onto it, and then put it in the USB port on the side of your TV. Make sure they are the only images on the flash drive to make your life easier.
Using the Viera tools, you can view the media images. When you select the first slide and it shows up on your TV, press the center button on the arrow pad to select slideshow. It will now loop the images. (Make sure in the settings menu of the slideshow screen that appropriate items are on - I'm not in front of my TV so I'm just telling you from memory).
Now, what I did was Break In for 100 hours using Evangelo's setting suggestion of low contrast, low brightness to let the panel ease it's way into the break-in, then I put on D-Nice's suggested settings in the panasonic setting thread (he suggests you use his general settings he provides for the slides THEN you apply the model specific settings below his first post), and did another 100 hours at his suggested setting. After that I applied the specific ST30 settings.
It was probably overkill using that method. For the first 100 I occassionaly watched content in zoom on movie channels for my sanity. But starting on a Sunday night, you can be ready for D-Nice's settings by Friday evening if you just run the slides 24 hours per day. I did not notice a spike in electricity bill.
