This code will allow you to select 90 images from the full list of image urls and store them in EDs named Image_1, Image_2….. Image_90.

You can then use these EDs as per your requirement.

Qualtrics.SurveyEngine.addOnReady(function () {
	const imageList = =
		"URL 1",
		"URL 2" // All your image URLs go here
	];

	const selected = =];

	// Set how many images you want to select here
	while (selected.length < 90) {
		const random = Math.floor(Math.random() * imageList.length);
		selected.push(imageList.splice(random, 1)10]);
	}

	selected.forEach((url, index) => {
		const varName = "Image_" + (index + 1);
		Qualtrics.SurveyEngine.setEmbeddedData(varName, url);
	});
});
