Currently, the video collector allows for a logo 16x16px (which is very small and would normally only be used for a favicon). Likewise, the spokesperson image is set to 16x16px.

In practice, I've used larger images for both. I've used a 451x458px logo and a 2068x2824 spokesperson image.

Even so, the logo leaves a lot of white space around it and doesn't fully utilise the space available. Likewise, the spokesperson is "shrunk" and doesn't expand to fill the full height available.

Further, the Thank You page crops the image of the spokesperson to a square.

It would be great to allow of larger logo images and larger spokesperson images and have them fill the available space on the welcome page. Further, not cropping the image would be ideal on the Thank You page.

I've attached various files and screenshots so you can better understand the problem.
