twitter-bootstrap center carousel image reguardless of screen size

Question

I have the following desires for a twitter bootstrap carousel:

1. When screen is bigger then carousel, I want the image centered.
2. When the screen is smaller than the carousel, I want to see just PART of the image. This part of the image should be centered.
3. At no point should the images be resized or scaled
4. The transitions should work.

My example below fixed problems 1-3.. but it breaks 4. I can easily fix 4 if I am willing to break 3, but that is no good.

Answer 1

This might help if you want the image to be re-sized according to the screen size of the device. The width = "100%" will do the job.

<img src="http://lorempixel.com/1200/600/abstract/2" width = "100%">

Answer 2

just add this to your css:

.carousel-inner > .item > img, .carousel-inner > .item > a > img {
    width: 100%;
}
