PopUp appearing when user clicks on text or image

Using PopUp. I need the popup to appear when the user clicks on an image or text (either one). I have checked other answers to this and just can't get it. I don't know enough java script or CSS... I have a popup happening when a page opens, that's great! But that's not what I need. Specifically - if I have a short line of text on a page, if I make it a link (or button) - how do I have a pop up activated?
Thanks

ps - I'm considering upgrading
