Thank you

You could probably store a list of colors in an array first.

Then, you can bind a change() handler for the select options, like this:

HTML:

<select id="products">
  <option value="0">Blue</option>
  <option value="1">Black</option>
  <option value="2">Red</option>
</select>

If you have an associative array, then you could replace the numbers by keys.

Then in JavaScript, you could do this:

$('#products').change(function() {
  $("option:selected", $(this)).each(function() {
     var index = $(this).val();
     $(this).css('backgroundColor', colorList[index]);
  });
})

where colorList is the array of colors.

Basically you need to have all color variations of that frame i.e. image of brown, red, white etc. frames as images.

For example your images could be named like: /images/frame_1_brown.jpg /images/frame_1_red.jpg /images/frame_1_white.jpg

On the select you have something like this:

<select name="color">
   <option value="/images/frame_1_brown.jpg" selected="selected">Brown</option>
   <option value="/images/frame_1_red.jpg">Red</option>
   <option value="/images/frame_1_white.jpg">White</option>
</select>

You have an image tag like:

<img src="/images/frame_1_brown.jpg" alt="Glasses" id="product-image"/>

Then the javascript will look like:

$('select[name=color]').change(function(){
   $('#product-image').attr('src', $(this).val());
})

Assuming that you use jQuery of course.

Basically this will change the image's src attribute when you change the selection of the dropdown.
