Displaying thumbs of adopted animals

Hi!
I am putting together an area to show adopted pets through the plugin. Is there a way to change the display of the pictures to a table say 6 pics across by 6 pics down? I have figured out how to change the picture sizr with css but I can’t get the table to work. Here is my css:

/*steve adopted-list*/

div.adopted-list div.dog div.name {
font-family: ‘Lato’, sans-serif;
font-size: 30px;
color: #2C3F13;
}

div.adopted-list div.dog div.images div.petfinder-thumbnails {
display: none;
}

div.adopted-list div.dog div.description {
display: none;
}

div.adopted-list div.dog div.features {
display: none;
}

div.adopted-list div.images .petfinder-big-img {
width: 50px;
display:inline-table;
}

and here is my shortcode:

[one_half last=”no”]
<div class=”blue-heading”>

Look Who Got Adopted

</div>
[shelter_list count=6 animal=”dog” include_info=”no” status=”X” css_class=”adopted-list”]

[/one_half]

Any ideas would be greatly appreciated!
Steve
