Too add a photo to your page use the following. You must put some text in the alt attribute otherwise the website will not validate.

< img src="image-url.jpg" alt="text description" style="width:Xpx; height:Xpx;">

Alternatively the style for the image can be manipulated in CSS.

You can also use an image as a hyperlink. For this you need to use the "anchor" (<a>) tag like so:

<a href="your-url-to-jump-to.html">
<img src="image-url.jpg" alt="text" style="width:Xpx; height:Xpx;">
</a>
