You do need to use fonts available to everyone:-

unless you use an image with text on it as you are trying to do. If the font looks OK in Photshop but not in an html page, has the size changed? Make sure the image is not resized when put into an html page. Photoshop should do what you want and it should display the same when in a webpage.
Code downloaded to my PC will be deleted in due course.
