Make SubCategory images clickable links...

Classic Contemporary Green template style.

I wish to make the subcategory images clickable links.
To see what I mean, use the drop down menu and click on "Glass Pipes" instead of one of it's subs.

They are clickable
select American Glass Pipes or love

Of major concern are your image sizes - one I checked was 3,264px × 2,448px (scaled to 200px × 150px)

You need to optimize your images for the web - they should not be more than approx 10K-20K per image

We are working to fix the image sizes... One concern we are having is some images show up as the same size when you click Enlarge image.

As the large displays at native size(whatever the image size is) you should matte all your images to a single large size
