To crawl thumbnails on YouTube, we use a interesting website that YouTube made for us for quick request for thumnail image.
1
| https://i.ytimg.com/vi/{YouTube_video_id}/maxresdefault.jpg
|
Firstly, we convert YouTube url to id by following code, and use “get” methed request the image.
Then, we stored the image in folder you like
using imagedown(YouTube_video_id, 'folder_name')
If there’s no such folder, then it will auto generate a new one.
