first shows image 1, then under it shows image 2
I hope I explained well.
Do you mean "first" in time, so a single part of the page shows a rotating series of images (with or without captions)? The word "under" makes it sound as if you want all the images to show at the same time, lined up from top to bottom.
A snippet of code wouldn't hurt.
