Page Layout ⇒ revtex4-1 | Empty second Column

[nahuelv]

Hi, I'm a newbie in LaTeX, and I have a little issue in the end of a long work. I need to put seven images at the end of a two column article. For some reason it just use the first column and leave the second column empty. I've tried with [h], [p], [!]. Please can anyone help me?
