Hello G_Lee. Welcome to Webmaster World.
A typical text link consists of an opening anchor tag with an HREF attibute pointing to the page to which you're linking followed by the link text followed by a closing anchor tag like this:
<a href="URLBeingLinkedTo">My Link Text</a>
Many times you want to have an image (instead of text) that is "clickable" so that when you click on the image it takes you to another page. This is achieved by placing an <img> element inside the anchor (<a>) element where the link text would normally appear like this:
<a href="URLBeingLinkedTo"><img src="URLOfTheImageToDisplay"></a>
This will display an image located at URLOfTheImageToDisplay and if you click on that image, you will be taken to URLBeingLinkedTo.
A common example of this is most web sites have a logo image in the top left corner of all of their pages. That image is typically an image link that will take you back to the home page.
