How to add pictures to an already added youtube video?

-okay i'm a bit behind on how to work computers. i was trying to make a video for my husband (not what you think haha). so i make the video, upload it to windows live movie maker, add photos, and music. then whever i try to upload it, or any other movie i make with that software, youtube tells me it doesn't recognize the file. well i'm getting a bit frustrated. is there any way i can add the two photos to the video after i've already uploaded it to youtube?Yes, of course, but first I think you should know, you can't upload Windows Live Movie Maker project file(.wlmp) to youtube directly, or convert .wlmp file to other format, because .wlmp file isn't an actual video file, just be a Windows Live Movie Maker project file, so you will meet this problem. To fix this problem, you must publish Windows Live Movie Maker project file(.wlmp) as an acutal video file first, just follow me, run Windows Live Movie Maker, open your .wlmp file, then click "Tasks" to show Windows Movie Tasks pane, then select "save to my computer", then next and next, you can publish the project file(.wlmp) as a wmv video file, then you can try to upload the wmv file to youtube directly, youtube supports right profile wmv file, if still fail to upload and process your made wmv file on youtube, maybe the wmv file is wrong profile, you can follow me to use Youtube Movie Maker to upload the wrong profile wmv file onto Youtube, it can auto convert any video files to the best profile and format then upload onto Youtube, and Youtube Movie Maker also can be used to edit/make and upload youtube videos from various videos, pics, musics, texts/lyrics, etc, such as add the two photos and music to the youtube video,as your said, better than windows Windows Live Movie Maker for youtube video creation. You can download it from makeyoutubevideo.com, hope it can help you.
