Troubleshooting

Abnormal with page scale

Add meta

<meta
  name="viewport"
  content="width=device-width, initial-scale=1,user-scalable=0, maximum-scale=1"
/>

for a large number of large images

If you group a large number of large images, img-vuer will load all image in the same group, so it will cause unnecessary mobile data traffic and slow the page down.

You can use preload option in this situation and img-vuer will only load the image you watched.

key

Should not use index as key for the component which is added v-gallery.
