Custom Single page

Hello all!

I have a problem here, I’ve created a Custom post type with name portfolio and assigns the single-portfolio.php file the display the objects.

Well now wish all the images of the portfolio that has a width greater than the height show at the top of the page, and those that had a height greater than the width at the bottom of the page (on separate pages, of course).

Would i have to create a new file or have some way I do this by editing the code of the single-portfolio.php?

Thank you!
