UI Layout issues to be addressed

[PersistentCoder7]

1. Ensure the container element doesn't have the max-width set to try to fit as many cards in a row as possible.
2. Set the thumbnail width to 50% initially, and on mouse-over, change the width to 100%.
3. Introduce an option so that the user can see the data without images, and we can turn on images later if required for elements that are shown.
4. Limit the number to 200 only, and provide an option to show all the videos.
