In what format should I supply words and photographs about my business for my new website?

We need these in an electronic format. Text should be sent in a Word document. Images should be in a JPG, GIF or PNG. We can also work with Photoshop or Illustrator files. Images should be equal or larger than we want to display. It is easy to reduce the size of an image, but you can’t enlarge it and have it look good.
