(Centering image) HTML/CSS

Hello. I'm using this HTML for a CSS based effect (codes provided). I have troubles fixing the image to align in the HTML. Image automatically positions itself on the left side.

Code:

<div class="imagepluscontainer" style="width:466px; height:1px; z-index:2"><a href="URL" target="_blank"><img src="IMAGE">
</a><div class="desc rightslide">
RANDOM TEXT
</div></div>

Code:

.imagepluscontainer{ /* main image container */
position: relative;
z-index: 1;
}

.imagepluscontainer img{ /* CSS for image within container */
position: relative;
z-index: 2;
-moz-transition: all 0.5s ease; /* Enable CSS3 transition on all props */
-webkit-transition: all 0.5s ease-in-out;
-o-transition: all 0.5s ease-in-out;
-ms-transition: all 0.5s ease-in-out;
transition: all 0.5s ease-in-out;
}

.imagepluscontainer:hover img{ /* CSS for image when mouse hovers over main container */
-moz-box-shadow: 5px 5px 5px rgba(0, 0, 0, 0.5);
-webkit-box-shadow: 5px 5px 5px rgba(0, 0, 0, 0.5);
box-shadow: 5px 5px 5px rgba(0, 0, 0, 0.5);
-moz-transform: scale(1.05, 1.05);
-webkit-transform: scale(1.05, 1.05);
-ms-transform: scale(1.05, 1.05);
-o-transform: scale(1.05, 1.05);
transform: scale(1.05, 1.05);
}

.imagepluscontainer div.desc{ /* CSS for desc div of each image. */
position: absolute;
width: 90%;
z-index: 1; /* Set z-index to that less than image's, so it's hidden beneath it */
bottom: 0; /* Default position of desc div is bottom of container, setting it up to slide down */
left: 5px;
padding: 8px;
background: rgba(0, 0, 0, 0.4); /* black bg with 80% opacity */
color: white;
-moz-border-radius: 0 0 8px 8px; /* CSS3 rounded borders */
-webkit-border-radius: 0 0 8px 8px;
border-radius: 0 0 8px 8px;
opacity: 0; /* Set initial opacity to 0 */
-moz-box-shadow: 0 0 6px rgba(0, 0, 0, 0.8); /* CSS3 shadows */
-webkit-box-shadow: 0 0 6px rgba(0, 0, 0, 0.8);
box-shadow: 0 0 6px rgba(0, 0, 0, 0.8);
-moz-transition: all 0.5s ease 0.5s; /* Enable CSS3 transition on desc div. Final 0.5s value is the delay before animation starts */
-webkit-transition: all 0.5s ease 0.5s;
-o-transition: all 0.5s ease 0.5s;
-ms-transition: all 0.5s ease 0.5s;
transition: all 0.5s ease 0.5s;
}
