One. What is the code to make an image click into a larger image?
If you see in my gallery, the images are small and I'd like to be able to have people click on them to make them bigger. =]

Two.This is my main layout image: Click to view.
As you can see by my website, I have three red dots that you must click to get to pages.
How do I hide that and make the words click-able?

Thanks. If I need to reword anything, please let me know. =]
