You can tailor your message according to an image or vice versa. After all, all images will not suit every message. For example, you cannot put the message- 'may you prosper and grow' on the image of a tiger prowling. It might look amazing, but the message sent by the image will not be in line with that of the writing.  So you should pick an image that echoes the message. In the case of the above quote, you can use images of sunrise, trees growing, high mountain ranges, birds soaring, etc. All these images convey growth and prosperity.
