Could anyone tell me how to make a photo to a page for coloring?

Thank you!

A few minutes of experimentation got me the attached file and image.
It’s not perfect by any means but there may be something to it if you persevere with adjustments.
The “Line Art” pixel layer was produced by merging the layers below and then inverting.

So that’s three different techniques.

My guess is that the specific technique to use would greatly depend on (but not be limited to):
* the image being converted – colours, complexity, etc.;
* what the result is going to be used for – quality prints, classroom playtime doodles, etc.;
* the time/effort that can be spent creating the results.

If this is just for someone to have something to colour in when they were bored I would probably go with this:
