попробуйте так

<template v-for="link, i in links">
            <img class="thumb-image" :data-src="link">
            <div class="gallery-content">
                <a :data-href="hrefs[i]"  target="_blank">
                <img :data-src="link">
                </a>
            </div>

        </template>
