Perfect, thank you. I merged the tracks and I have the slideshow completed. Now I have one last question, although not audio related, however I thought this might be easier than posting a new thread. Anyways, I plan on uploading this to YouTube, and I don't know whether to export the slideshow from iPhoto to a 320x240 size, or 720x480. Also, is it normal for the file size to be large? (before music, it was 133MB, so it'll be even bigger now...)
