In my opinion i would:

Make the images better quality. Sure, a fast loading website is ideal, but I still want to see good quality pictures when I view a website.

Find a colour scheme, they do wonders to help make a website look good.

Make the website template consistant, I personally don't think a website should look completely different on each page, plus if you use the same template, you'll be using many of the same images which will save time on loading each page.
