in your css set image width:100%

.carousel-inner>.item>img, .carousel-inner>.item>a>img {
        display: block;
        height: auto;
        max-width: 100%;
        line-height: 1;
        margin:auto;
        width: 100%; // Add this

Theres also an easy way to implement this right in the carousel html structure. Every time you insert an img as an item, while still being inside the tag, add style="width: 100%". so it would look something like this.

<div class="item active">
    <img src="img1.jpg" style="width: 100%">
</div>

<div class="item">
    <img src="img2.jpg" style="width: 100%">
</div>

<div class="item">
    <img src="img3.jpg" style="width: 100%">
</div>
