Jquery, Click / If Else function, Not working

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta http-equiv='Content-Type' content='text/html; charset=UTF-8'>

<style  TYPE="text/css"> 

    .show                                       { display:block; }
    .hide                                       { display:none; }

</style>
</head>
<body>
<script type="text/javascript">
$('#portweb').click(function() {

    if ('li[value*=web] img'.hasClass("hide")) {
        $('li[value*=web] img').removeClass('hide').addClass('show');
    }
    else if ('li[value*=web] img'.hasClass("show")) {
        $('li[value*=web] img').removeClass('show').addClass('hide');
    }

});
</script>

<a href="#" id="portweb">Web</a>
<br />

        <ul id="portfolioWrapperSet">
            <li value="web dev"><a href="#"><img src="images/portfilio/ph1.jpg" class="hide" /></a></li>
            <li value="web packaging print media"><a href="#"><img src="images/portfilio/ph2.jpg" class="hide" /></a></li>
            <li value="tv packaging print media"><a href="#"><img src="images/portfilio/ph3.jpg" class="hide" /></a></li>
            <li value="web packaging print media social"><a href="#"><img src="images/portfilio/ph4.jpg" class="hide" /></a></li>
        </ul>


</body>
</html>

So the problem im having is actually getting my function to remove the '.hide' class then add the '.show' class through my if statement.

Try changing your if conditional to something like this: 

if ($('li[value*=web] img').hasClass("hide")) {
        $('li[value*=web] img').removeClass('hide').addClass('show');
    }
    else if ($('li[value*=web] img').hasClass("show")) {
        $('li[value*=web] img').removeClass('show').addClass('hide');
    }

You are trying to manipulate the DOM before it is ready. Try wrapping your code in a document.ready statement. Also in your ifs you are trying to call the hasClass method on a string which is not defined:

$(function() {

    $('#portweb').click(function() {

        if ($('li[value*=web] img').hasClass("hide")) {
            $('li[value*=web] img').removeClass('hide').addClass('show');
        }
        else if ($('li[value*=web] img').hasClass("show")) {
            $('li[value*=web] img').removeClass('show').addClass('hide');
        }

    });

});

You ought to use the .show() and .hide() methods really as what you're trying to do is what they were designed for.

You need to wrap your code into a function that will get executed when the ready event is raised

$(function() { /* code here */ });

So it should be like so

$(function() {

    $('#portweb').click(function() {

        if ('li[value*=web] img'.hasClass("hide")) {
            $('li[value*=web] img').removeClass('hide').addClass('show');
        }
        else if ('li[value*=web] img'.hasClass("show")) {
            $('li[value*=web] img').removeClass('show').addClass('hide');
        }

    });

});
