Which software are you using?

Here is an easy example what I do in Music Maker, you can try in your software if possible.

Import or add photo on Timeline or work space.

Then add audio/music.

To adjust the photo with the music drag the photo to the right or left. Or in your software if you got something like stretch try that and see.

You can also do the same with music, drag right or left to adjust with the photo if needed.
