You could look at the multiimage code. All the logic and so on is there

I've got to be honest it's like trying to read klingon lol

Just ignore the theory and focus on the code.

So far i have this

var rand = new Random();
            var files = Directory.GetFiles(@"C:\ProgramData\Team MediaPortal\MediaPortal\thumbs\MovingPictures\Backdrops\FullSize", "*.jpg");
            string filename = files[rand.Next(files.Length)];
            GUIPropertyManager.SetProperty("#A.picture", filename);

Which randomly picks an image in the folder i've set ( working great in basic home ) but i cant work out how to get the image to change every 20 seconds or so ?

You need to set timer i think and a method to update property value on every time expiration. I cant be more specific writing from phone

If you look in the multiimage file you see this

private readonly StopWatch _imageTimer = new StopWatch();
and lower down

if (_imageTimer.IsRunning && _imageTimer.ElapsedMilliseconds > _timePerImage)

_imageTimer.Stop();

_imageTimer.StartZero();
this will let you keep track of when to switch image

Stopwatch is appeared to be vista+ according to google so i suggest to use timer from System.Timer or System.Timers

Hi!
This look like fun, so I tried to do something simple. Adding the dll, and the property that is it use is : #ImagePlugin.Image

Place the plugin i process plugin folder. Changing picture every 20s. Needs a folder C:\ProgramData\Team MediaPortal\MediaPortal\ImagePlugin

Pasting source soon.[DOUBLEPOST=1420896086][/DOUBLEPOST]Ther is nothing random at all here, but that should be easy to fix. Place your images in the above mentioned folder ImagePlugin
