Hi targendaz2. Welcome to SitePoint.
Firstly, you need to create a web-friendly version of that image (you can use Save for Web in Photoshop.) Consider, say, 300kb as a maximum image size for the web, though it should be a lot smaller than that ideally. %MB is out of the question.

It can also be done with modern CSS (version 3), though this isn’t yet supported by all browsers:
Thank you. I didn’t know there was anything out there that could do that.
