In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.
Include a note directly beneath the image acknowledging where it comes from, beginning with the word “Note.” (italicized and followed by a period). Include a citation and copyright attribution. Don’t title, number, or label the image as a figure, since it doesn’t appear in your main text.
