Answer 1

This is one way to do it:

Fiddle here: http://jsfiddle.net/4Mvan/1/

HTML:

<div class='container'>
    <a href='#'>
    <img class='resize_fit_center'
      src='http://i.imgur.com/H9lpVkZ.jpg' />
    </a>
</div>

CSS:

.container {
    margin: 10px;
    width: 115px;
    height: 115px;
    line-height: 115px;
    text-align: center;
    border: 1px solid red;
}
.resize_fit_center {
    max-width:100%;
    max-height:100%;
    vertical-align: middle;
}

Answer 2

It is because there is one p tag with images.

Which is:

<p class="caption">Amitabh Bachchan photos from different ages.</p>

Make there height:0 . like:

.caption {
    height: 0;
}

And give padding to image like following:

.profile-pic {
    height: 200px;
    padding: 10px 0; //here.
}
