[Showcase] Add posters galore (react-admin)

I think that's a good showcase of what material-ui can do.

Thanks for the great work! ❤️

Hi, thanks for the submission.

Please could you make the image 900 x 650, JPEG @ 40% quality to be consistent with the other entries?

@fzaninotto Looks good!
@mbrookes I agree a <100 kB image is acceptable, 7.29 MB is not compounded to x20 showcases.

As you see fit, I made the changes.

I too think that 7MB per picture is too much if there are more than 20, but I think that the solution is otherwise. The screenshots are too big IMO. The showcase page is so tall that I get tired of scrolling before I get to the half.

I think this page would really benefit from smaller screenshots, allowing 2 to 4 screenshots per row. Not only would it show more sites to users with less effort, it would allow gifs instead of only jpg. And considering Material Design is really into microanimations, I do think that a gif sells more than a still picture.

Lastly, maybe the appList could have both an image and a video link, the video being lazy loaded when the image is on screen.
