After you have uploaded your page edit out any extra coding for your images. Make sure you double check all image coding for the file name as listed in your computer. Make sure you view your page in the E-Browser and the Netscape browser, they don't always cooperate with each other and you may have to adjust some coding or make a statement on the page of which browser shows your page best. Screen captures are great fun to work with. It can be a bit frustrating until you learn the technique.
Some people get it right away others take more time to learn how to work with it.
Keep in mind that it will also depend on your own computers capabilities.
