css - Portfolio page loading images on top of each other

Question

Forgive me if my problem is easily solvable.

My photography page loads my portfolio thumbnails on top of each other. It doesn't seem to fix itself unless I resize my window size, or refresh the page. If I clear my history and go back to the site the positioning is all messed up again as well.

When it loads wrong

How it should look
