Pages --- picture prints with a line through it

Question

I copied pictures into a Pages document and everything looks good on the screen. When I print it, a line shows up where an "alignment guide" would be showing guides at object center.
It is very light but also very noticeable on the paper. When on the screen it only show up when I move the picture around. When moving on the screen it was blue and I changed the alignment guide color to red to confirm that it is the alignment guide.
I've checked the show guides at center, guides at edges, and had neither guides checked. When moving pictures on the screen these have the expected impact. BUT the light line shows up on the printed page at the center location for all three options.

Answer 1

A bit more information:
- The line is sort of colorless. Only on screen when moving about was it blue or red after I changed it.
- The doc has 3 pictures. The one with the line through it (under my wife's nose) doesn't seem to go on to the picture next to it. Almost as though a power greater than I was tweaking my wife.
- My last attempt is to have alignment turned off and the third picture is the last to moved. It includes some buildings and signs with horizontal lines. When printed no lines are visible on this third picture. Unfortunately, I now get a couple vague lines, lighter than prints that go this thing going, still in the first picture with the wife and grand kid. Seems like this also takes the printer out of the equation because the lines move.
This is to be copied as a Christmas letter which will probably make the lines even harder to see, so I'm hoping that it will pass the wife's muster. I'm going to give up for now though will check back to see if any other ideas show up.
Thanks much for your attention and help!
