How do I paste text below the image I pasted.

When I pasted the image I pasted some text next. It went above the image and I want it below, how do I do that? And also, I want to also paste another image below the first. I have it in landscape format.

There are several possibilities, but the two favourites would be

Click and hold on the image to move it to your desired position in the text.

You can place the image in the text flow where you want it. Right-click on the image and select Anchor > As Character, the image will probably move to somewhere undesirable. Select the image and Cut it (Ctrl+X), insert your cursor where you want you image in the text and paste it (Ctrl+V).
