I would make a powerpoint/ slideshow of images and add a song please??

I want to make a presentation of pictures, with a song playing at the same time, but have no idea how to do it

You can you Windows Movie Maker if you have it on your computer (some versions of XP, Media Centre Edition and Vista).

If you have Windows XP you can download Photo Story for free. I've used it a few times and found it easy enough to use.

Go to Insert, Choose "Movies and Sound", then "Sound from File" and basically follow the prompts. If you get stuck try using Powerpoint Help - it usually is quite helpful. I spend most of my working life using Excel and can do complicated things with it in minutes, when it comes to presenting my stuff in Powerpoint it can take me forever but I usually manage it with the aid of the Help functions.

Thanks. I will have a fiddle round with it, see what I can do

Yep, window's movie maker is probably the easiest.
