Замена блока на фотографию при наведении курсора

Пример:

HTML:

<div class="items">
	<div class="item">
		<a href="#item">
			<svg preserveAspectRatio="xMidYMid slice" viewBox="0 0 300 200">
				<defs>
					<clipPath id="clip-0">
						<circle cx="0" cy="0" r="150px"></circle>
					</clipPath>
				</defs>
				<text dy=".3em" x="50%" y="50%">
					Фото 1
				</text>
				<g clip-path="url(#clip-0)">
					<image preserveAspectRatio="xMinYMin slice" xlink:href="/photo.jpg"></image>
				</g>
			</svg>
		</a>
	</div>
	<div class="item">
		<a href="#item">
			<svg preserveAspectRatio="xMidYMid slice" viewBox="0 0 300 200">
				<defs>
					<clipPath id="clip-1">
						<circle cx="0" cy="0" r="150px"></circle>
					</clipPath>
