Solid colored text just doesn’t have the same artistic appeal as text filled with a background image or texture, such as wood grain, a painted background, or even a sunset. Background images are plentiful on stock art websites and easy to snap with your camera or cell phone, so there should be no trouble coming up with an interesting image.
To add an image to text, first set some type in a font that is thick enough to display an image inside. Then set both the foreground and background color to none. Select the Draw Inside button at the base of the Tools panel, and Illustrator will display a dotted line around the bounding box corners. Choose File > Place, navigate to the image you wish to place inside the text, and click Place. Reposition the text over the image as needed, select the Draw Normal button at the base of the Tools panel, and you’re done!
