var curtext = \"View large image\"; function changeSrc() { if (curtext == \"View large image\") { document.getElementById(\"boldStuff\").innerHTML = \"View small image\";

var curtext = "View large image";
function changeSrc() {
    if (curtext == "View large image") {
        document.getElementById("boldStuff").innerHTML = "View small image";
        curtext="View small image";
    } else {
        document.getElementById("boldStuff").innerHTML = "View large image";
        curtext = "View large image";
    }
}

var curimage = "cottage_small.jpg";
function changeSrc() {
    if (curimage == "cottage_small.jpg") {
        document.getElementById("myImage").src = "cottage_large.jpg";
        curimage = "cottage_large.jpg";
    } else {
        document.getElementById("myImage").src = "cottage_small.jpg";
        curimage = "cottage_small.jpg";

I need help, how to put as one function with two arguments? That means when you click, the image and text both will be change. Thank you! Bianca

function combined(curtext, curimage){
  if(curtext == "View large image"){
      document.getElementById("boldStuff").innerHTML = "View small image";
        curtext="View small image"; 
      }
      else{
       document.getElementById("boldStuff").innerHTML= "View small image";
           curtext="View large image";    
  }
  if(curimage == "cottage_small.jpg"){
       document.getElementById("myImage").src="cottage_large.jpg";
       curimage="cottage_large.jpg";
        }
      else{
       document.getElementById("myImage").src="cottage_large.jpg";    
       curimage="cottage_small.jpg";
  }
}

Make a new function that calls them both, and rename them to something unique.

var changeCombined = function() {
    changeTxt();
    changeSrc();
};

function changeTxt() {
    var node = document.getElementById("boldStuff");

    if ( node.innerHTML == "View large image") {
        node.innerHTML = "View small image";
    } else {
        node.innerHTML = "View large image";
    }
}

function changeSrc() {
    var image = document.getElementById("myImage");

    if ( image.src == "cottage_small.jpg") { 
        image.src = "cottage_large.jpg";
    } else {
        image.src = "cottage_small.jpg";
    }
}

This also removes your dependency on globals.
