alt attach book button buy click image img immediately picture site src url

I have a Buy Now button on my site. Can I attach the URL to a picture of the book? So that when they click the picture of the book, they can immediately uy the book. What I'd have to leave out is: <img src="https://www.e-junkie.com/ej/x-click-butcc.gif" border="0" alt="Buy Now"/> Because I'd have in there my own image. Please let me know if I can do that.

Sure, you can do that.
