Make sure your images display properly. Check your spelling. Grammar is very important. Keep your page simple. Unless your page is centered around graphics, pictures should be kept to a minimum.
Nobody wants to wait for huge image files to load.
Save those for your second page. Place as much information about your subject possible. And be sure to say it all in the first two or three paragraphs. Choose colors wisely. Red print on a colored background can be very difficult to read.
