I'm putting an .mp3 file (podcast) into Movie Maker so that I can make a complimentary YouTube video. While I'd like to incorporate some images and such, I find that I can only make a single .jpg or .png stay on screen for a maximum of 30 seconds?  I've seen lots of audio-only podcasts that run with just a logo for 30 min. to an hour.  Is that possible in Movie Maker ...

So far, I've just copied and pasted the logo for our cast over and over and over again (approx. 80 times) to get the necessary length for the audio file.
