The mind wandering means you're not chanting. The chant intends to keep the mind busy. Just come back to the chant. You're not the only one with a conscious mind that is happier wandering off when it's not needed. The mind will wander off, just notice and when you do bring your focus back to the chant and page flipping because that reminds you of your intention to be focused on the book for the purpose of PhotoReading it.

If you're using the mind to visualise you're taking away the visual processing the mind needs to do for PhotoReading. That's why you look at the text as you flip pages. Visualising, is the same as letting the mind wander off. It wanders to something visual and starts the internal conversation later. Reading and visual memory sorting is done with the same part of the brain.

If the relax chant doesn't do it for you, chant the alphabet, or say a nursery rhyme, or repeatedly state your purpose, I suppose you could even say a prayer, I've never tried it and can see that working. You will notice all the techniques keep the mind busy by using auditory techniques.

Now for my challenging question to you.

If you think it would work better for you, why don't you try it?

It will either work or it won't.

My view if you do what you describe, you won't be PhotoReading the book any better than when the mind wanders, because you're giving the visual processors permission to wander off to something of a visual nature and you're trying to PhotoRead which is a task that requires visual processing.
