Resolution is how we measure the quality of an image. Images are made up of tiny little pixels or dots. Image quality can be determined by how many pixels make up your image. This is called "ppi" (pixels per inch) or "dpi" (dots per inch). Because your images are to be viewed on a screen, all web graphics should be no larger than 72 ppi. Anything higher has no improved effect, and only creates longer download times.

For your audience to view the same font (an unique set of type characters) you see on your own screen, they must also have the same font installed on their own individual computers. Otherwise, their browser will instead show a substitute font, which designers have no control over.

For this reason, be more conservative with your choice of fonts. Display only what the general public already has on their computers. If you're looking for a contemporary look, use standard fonts like Helvetica or Arial. If you're looking for a more sophisticated look, use fonts like Times or Verdana. If you absolutely MUST have everybody see your creative font, then convert the selected text into a graphic. Use this option sparingly, though, since it will increase your web pages' download time.
