Players' list gallery alignment

Hello,
On the team page I would like to display the photos of the players. For that purpose I chose the gallery option in players list. The gallery displays but the pictures are not aligned and it’s difficult to play with css with it because h4 and dt (the code below) are not wrapped in one html tag ex div.
I would appreciate any help for that matter.
Many thanks for your help!

<div class="sp-template sp-template-player-gallery">
    <div id="sp-player-gallery-83" class="gallery galleryid-83 gallery-columns-3 gallery-size-thumbnail">
        <a name="group-0-goalkeeper" id="group-0-goalkeeper"></a>
        <h4 class="player-group-name player-gallery-group-name">Goalkeeper</h4>
        <dl class="gallery-item">
            <dt class="gallery-icon portrait">
