How to get YouTube thumbnail images in just 1 click
The other day while working in a solution to create a video gallery I had the necessity to get the thumbnail image of YouTube Videos. I had a look to the API but that required the use of an API key and the manual configuration of the user, after a while I found out that the images are publicly available for everyone to use in 5 different resolutions.
In this article you will find the generic URLs for each resolution and a small tool where you can paste the URL for your video and get the thumbnail and the URL for each image.
