Youtube Thumbnail Search

Want to know where the source of youtube thumbnails is?
Have you ever seen an awesome clickbait thumbnail and wanted to get one?
Here I created a script which is not very useful but will be useful sometime :)
just click the magnifying glass icon in the top left corner of the thumbnail and you will be directed to the yandex image search with image results :)

v0.6 i rewrite the code.
TIPS: if you wana click the button on short video, make sure you cursor enter from above of video, idk why when a preview is playing (your cursor hover the video) and then you click the button, it will give you blank url or wrong thumbnail url, so ya just make sure you cursor is enter from above,again this only afected to short video.
