Double rendering of one fetch

Hi everyone,
I’ve been working on a personal portfolio, and I would like to show random photos on my Flickr account.
So here its the whole of this section of my react.

import './Flickr.scss';
import React, { useEffect } from 'react';

export function Flickr(props) {
	function Myphotos() {
		let img1 = { photoid: '', photosecret: '' };


		let urlflickr = `https://www.flickr.com/services/rest/?method=flickr.people.getPublicPhotos&api_key=3e7dff85a13f1e234c02931ac56a4cd4&user_id=69387047%40N04&per_page=43&page=1&format=json&nojsoncallback=1`;
		fetch(urlflickr)
			.catch((error) => console.error('Error:', error))
			.then((response) => response.json())
			.catch((error) => console.error('Error:', error))
			.then((response) => {
				let random1 = Math.floor(Math.random() * response.photos.photo.length);
				
				img1.photoid = response.photos.photo[random1].id;
				img1.photosecret = response.photos.photo[random1].secret;
				

				if (img1) {
					let urlimg1 = `https://live.staticflickr.com/65535/${img1.photoid}_${img1.photosecret}_b.jpg`;
					document.getElementById('uno').style.backgroundImage = `url(${urlimg1})`;
				}
			
			});
		setTimeout(Myphotos, 15000);
	}

	function Followmeflickr() {}

	return (
		<div className="flickr">
			<h2>FLICKR PHOTOS</h2>
			<div class="photos">
				<div className="photo" id="uno" />
				
			</div>
			</div>

			<script>{Myphotos()}</script>
		</div>
	);
}
export default Flickr;

So, I can see one first photo that is changed really fast and after stay 15seconds until I see two photos again.
I’ve been working on it, but couldn’t find the answer.
I tried to have it like onLoad={Myphotos}

I would like to know if someone more had this problem. Thanks
