cipher - There is a secret message in the picture

There is a secret message in the picture, can you find it?

This picture is from the 50 trillion dollars challenge from the free ebook "Muko and the Secret". This one is already solved so I hope I do not violate any rules here.

Best regards, Greg

Answer

Could the solution be

IMAGE? The second puzzle that was posted from this book was solved using some morse code cleverly incorporated into the art. Assuming that this puzzle would be similar, I searched this puzzle for anything morse-code like and noticed that there are some strange lines that go across the bottom edge of the pacifier, here.They read "short short long long short long long long short short". Splitting the morse code up where there is a slightly bigger gap, and translating to English, we get the word IMAGE.
