You can easily do this using jQuery.
However this is pretty simple stuff so I suggest doing a bit of reading and practice on basic html.
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#submit").click(function(){
$("#hidden").show();
});
});
</script>
<style type="text/css">
.hidden {
display: none;
}
</style>
</head>
<body>
<form><input type="submit" id="submit"></form>
<div id="hidden" class="hidden">IMAGE</div>
</body>
</html>
