I have a still photography picture that I would like to add audio to and then upload to YouTube. The picture is already on my computer. I use MS Live MovieMaker, and my computer is equipped with a webcam and audio recording. I have seen this sort of thing on youtube--just a still picture with audio playing. Thank you.

I have never done such a thing but if I were to try I would guess you would need to create an avi or wma file where all the frames are all just the one picture, and it would have to be long enough so the audio didn't keep going after the last frame. If the audio is 2 minutes long, you would have to create a single picure of so many frames to equal 2 minutes play (some of the frames could actually have text added for effect) then use something like virtual dub mod to load your avi and then add the audio in the streams section (v dub likes mp3 for audio and avi for video) and with both audio and video set to DIRECT STREAM you can mux the two together pretty quickly since direct stream copies, and does not re-encode.

Then after playing around test the video before you upload.

Its also possible you might be able to use just one frame of the picture converted to avi and then see if the picture remains active as the audio plays. If it just shows as one frame then the audio continues or the audio will not add to such a small video, the above is the only way.
