I would like for the video and photo thumbnails both to be this size or larger. I think about four times the default size would be good. How do I do this? I searched forums, but couldn't find a direct answer. I tried changing things in admin and nothing happened. I was thinking that if it is four times as large as default, it wouldn't change the design too much since everything is in squares. plus, larger thumbnails attract more users. To me, I think it makes people want to click on it more.
I would also like to take away the spacing between the thumbs and take away the username and title/description from the bottom of the thumbs. I just need it to be a wall of thumbs for video and a wall of thumbs for photos. Thumbnails should be touching each other on all four sides in this case. I attached a photo of the wanted results to this post.
