This is a test page for the photos.
Here is one way to make a caption. But, if you'd like the text to have the font style similar to the other pages, just copy and paste those text boxes.
Shortcut keys for copy is command and C on the mac. I think it's Alt and C on the PC.
Shortcut keys for paste is command/alt and V.
Just a note. If you copy and paste from one page to another, it usually pastes at the exact same point/place that it was at on the previous page. This helps immensely when you're making a title that you would like to be the same distance from the header on each page.
Here are some other interesting things you can do with your photos.
