There are a few ways to align elements:
Use a ruler: To line up elements with a ruler, go to View, Rulers, Show Ruler. A red grid will appear on the page of your project and you can align the edges of photos and text boxes using the lines. You can also select Black, Red, or White under Show Ruler if you would like your ruler to be a different color. To remove your ruler, go back to View, Rulers, and click on "Show Ruler" again - your ruler will turn off.
You can also use the "Position" section under "Layout" in your Tool Box to line up your elements. If you want them to line up vertically, just make sure that your "x" is the same for each element. For horizontal alignment, use "y".
My favorite way to align elements is using my "Shift" key. By holding down "Shift" on my keyboard at the same time as I click on the elements I want to play with, I hi-lite all of the elements at the same time. Then, in the bottom half of "Layout" in the Tool Box, I can use the "Align" and "Distribute" buttons (top, center, bottom/horizontal or vertical) to line up and equally distribute my elements! The "To" buttons are "to the group", "to the first item" or "to the page" - this refers to if I want to align/distribute my object(s) in reference to each other or to the entire page.
