title: How can I load a file of thousands of images in html?
body: <p>Now I have a local folder with 12989 images. The total size is 410MB. On the other hand I have another csv dataset, which has each image's name, main color and some other information. 
  So, how can I visualize all the images without calling one by one? Thank you!(if possible, I prefer using d3.js. )</p>
