1) Add radio buttons below an image for users to click, and when clicking the image should become larger or smaller.

Tips: You can check the radio button by using Boolean 'checked' attribute. For example:

if (document.getElementById("ZoomIn").checked)

The below image is how it should look.

2) Make a photo slideshow using JavaScript.

Make a photo slideshow that that contains 2 or more images. It should includes a previous button, next button, ex. "Image 1 of 2", and a brief description.
