Url of large image of a YouTube video

Question

I'm interested in getting a preview image of a youtube video for my application I'm using the url to the previews:

http://img.youtube.com/vi/EqWRZrupLrI/0.jpg

but this has little two black rows, up and down, and I wish it were bigger. I have read that the 0 is the bigger picture.

anyone know if it is possible to obtain a url with a better image?, for my project, I need the image is on a url

I appreciate the help

Regards :)

Answer 1

0.jpg is the full-size 480p thumbnail and there is no bigger thumbnail except for full HD videos (maxresdefault.jpg).

But why do you expect a bigger thumbnail for such a video ? Your video example has a resolution of 240p, the thumbnail is already much bigger than the video resolution.
