Answer:
If Murray is creating a new website to showcase his photograph then he should first learn HTML. Using HTML, he can easily create an image gallery.
Step-by-step explanation:
Murray should learn HTML to showcase his photographs. Because using HTML, the image gallery can be developed. However, CSS learning is also essential for him, if he wants that website design should be responsive. As we know that, without HTML, CSS is useless. Therefore, he should first learn HTML. Then he would learn CSS if the requirements are related to the design and responsiveness of the website.
JavaScript is used to trigger events in this scenario. For example, show a response to the user, if someone clicks the image. Then he should learn JavaScript. While ActionScript is not necessarily to learn because it is developed for website animation.
