Aligning multiple images horizontally in the center of a div

I have a div and I want to align in the center of that div multiple images. All of the images have the same height and width of 16px. The problem is that I can either center them and have the extra space below but when I use the display:block to remove it, they are aligned to the left again. Here's my code:

div which I want to contain the images:

.cell{
    position: relative;
    float: left;
    width: 300px;
    min-height: 22px;
    border-bottom: 1px solid #000;
    border-right: 1px solid #000;

    line-height: 22px;
    font-family: Arial, Verdana;
    font-size: 12px;
    color: #000;
    text-decoration: none;
    text-align: center;

    margin-bottom: 2px;
    margin-right: 2px;
}

The above class has the properties needed in general. So I want to create a class for the img elements so that they can be aligned one next to each other and all together aligned horizontally.

Any working suggestions?! :)
