multiple images on one page

[waterhorse]

I have used Gimp minimally for many years, mostly to rescale images and/or converting file formats.
I have never used layers.
I simply want to paste several images on page (8.5x11 sheet of paper) to print them.
In my recent attempt I think I was able to paste another into the file, but I'm guessing they are on top of each other. If so I don't know how to move the 2nd one pasted to another position in my imaginary grid.
I would accept any reasonable way to do this whether it involves layers.

Thank you,

Paul

Using File > Open as layers you can add images as new layers (one by one but you can also select multiple file in one go).

To move them you can use the move tool ()

You can align them easily using guides

You can scale and move them to fit any space using the scale tool (), probably with Keep aspect set to avoid stretching/squishing.

Don't forget to save as XCF from time to time.

If you have the gimp plugin 'G'mic-Qt' With the filter montage under arrays and tiles, you can probably do this in one click - depending if your pages are the same size etc.
You may have to use the custom layout for size or output as new active layers if you need to move them still.

If you are going to move your layers around you need to first have the appropriate layer selected. Shown by a highlighted layer and by yellow and black dashes around the layer that is on canvas. 
The other marking that you will have another time if you 'alpha to select' a layer is marching ants.
In my illustration below the layer that is highlighted by a white surround (In the layers list) has a  yellow surround on the canvas. That is the one you move.
