Choose a photo, one that has quite a bit in the top left corner. When you join the words with the photo, it copies from the top left corner down. I have tired this on several pictures only to have it look bad. So I have come up with two ways to accomplish the same thing.After you have your photo, choose a chunky fat font and type your word or words. Match the top of the words to the bottom of the photo. Next click on the words then hold the Shift key down and left click on the photo. You then need to click on the Layout tab at the top and then Flatten the two to make them one Element. Next use the same photo and click on the bar that is on the right side of the photo and choose "Fill the selected element with this photo."
The other way to fill the words with a photo, is to use a chunky fat font. Type your words and then choose Layout and flatten the word. Then click on the photo bar and choose "Fill the selected element with this photo."You then can line up the word with the bottom of the photo.
