I guess that's about as clear as mud if you're just starting out, sorry! :oops Let me know if this explanation helps. :scratchchin
Here goes:
Let's say you have an image at your web site located in the following place:
http://mycrochetstuff.com/images/button.gif
And you want to link it to:
http://somecrochetsite.com/
Use the following code:
<a href="http://somecrochetsite.com/"><img src="http://mycrochetstuff.com/images/button.gif" border="0" alt="Some Crochet Site" vspace="3"></a>
You don't have to use these parts, but I like to:
border="0"
alt="Some Crochet Site"
vspace="3"
If you don't use border="0", there will be a border around your image the same color as the rest of the links on your page.
The alt="Some Crochet Site" is the text that displays when someone puts their mouse over the image.
The vspace="3" keeps a little vertical space above and below the button so it doesn't smash up against other buttons or text. It doesn't have to be 3; it could be larger or smaller. You can also specify hspace="3" for horizontal space.
