HTTP Requests Question

I couldn’t find a clear answer to this so I was just wondering if someone can clarify this for me.

Lets say you have image a, and it’s a repeatable image on your site (in my case an arrow). Is each image tag an HTTP request or does it become cache accessible at this point?

If I were to put it in CSS would it be again 1 HTTP request or be x many HTTP requests where x = number of times the element appears in the HTML?

I hope that makes sense?

Thanks for any help.

1 image file = 1 reuqest, doesn’t matter how many times you use it on the page. That’s why CSS image sprites are used more often. You create an image which is used in mane places.
