Help Please! How to make Image Overlay Ads in Blogger

Hello, I've been searching for a way to embed adsense on image but I'm confused. Noob blogger here. I know, it's not allowed but I'm just curious. Please help. Thanks!

Your best bet is to have ads on your webpage and link an image to the clickthrough. Basically, right click on an ad on your page and click "Copy Shortcut". Then, use an image a link somewhere else on your page.
