You can adjust the speed* at which your creation should play, but sorry you cannot time the music of your creation to specific photos within the creation. When you are working on a creation on your desktop, it is saved on the hard drive of your computer. The timing is more in sync with the photos because everything is local on the computer. Once you send your creation, it is stored on the Smilebox servers. When you playback the sent/blogged creation, we can't guarantee the timing of the music with the photos, because it depends on the speed of the internet connection.
We apologize for any misunderstanding.
As a sender of Smilebox creation to be exactly sure that your music and your photos are coordinated, you can also save the creation as video file (premium feature) and then email or blog the saved file. This video file will play in sync, since it is a prerecorded file. To learn how to save the creation as video file please refer our Forum article on – Can I save the creation as video file?
* To find the designs what will let you adjust the speed of your creation please refer our article - How do I adjust the "Speed" of automatic playback in my slideshow?
