Specifying Image Width and Height

Because text moves over the Internet much faster than do graphics, most Web browsers will display the text on a page before the images. This gives people something to read while they're waiting to see the pictures, which makes the whole page seem faster.

You can make sure that everything on your page appears as quickly as possible and in the right places by explicitly stating each image's width and height. That way, a Web browser can leave the right amount of space for that image as it lays out the page and return for the actual image file later.

For each image on your page, use Paint Shop Pro or another graphics program to find out the exact width and height in pixels. (In Paint Shop Pro, this information appears at the bottom-right corner of the main window when you move the mouse over any part of an image.) Then include those dimensions in the <img /> tag, like this:

<img src="myimage.gif" width="200" height="100" />
