I have the following code where the images are fetched from the database. It keeps going breaking the DIV and overflows. What I want is when the images reach the end of the DIV it should break and start a new line. But I have no idea as how to achieve this. Please help me guys.

Code

<div class="inline-flex">
    <?php while($faf = $prooq->fetch()){ extract($faf); ?>
       <div class="image-container"> <img class="myThumb" id="myImg" src="proofs/<?php echo $pr_image; ?>" alt="" width="160" height="100">
          <div class="image-text">shreyansh ($8.75)<br>
          <span><?php echo date('jS M, Y (h:i a)', strtotime($pr_uptime)); ?></span></div>
       </div>
       <div id="myModal" class="modal"> <span class="close">&times;</span> <img class="modal-content" id="modalImg">
          <div id="caption"></div>
       </div>
    <?php } ?>
</div>

CSS

.image-container {
    width: 163px;
    height: 100px;
    padding: 0px 0px 65px 0px;
    font-size: 12px;
    text-align: center;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    margin-right: 13px;
}

.image-text {
    margin-top: 5px;
}
.image-text span {
    color: #ddd;
    font-size: 9px;
}
.inline-flex {
    width: 100%;
    display: inline-flex;
}

I found the answer to my solution. Added an extra DIV with class .proof-container with property position: relative; and wrapped all elements inside it and added a property float: left; to .image-container. That's it. Below is the code:

CSS:

.image-container {
    width: 197px;
    height: 120px;
    padding: 0px 0px 65px 0px;
    font-size: 12px;
    text-align: center;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    margin-right: 10px;
    float: left;
}

.proof-container {
    width: 100%;
    position: relative;
}

HTML:

<div class="proof-container">
        <?php while($faf = $prooq->fetch()){ extract($faf); ?>
        <div class="image-container">
          <img class="myThumb" id="myImg" src="proofs/<?php echo $pr_image; ?>" alt="" width="160" height="100">
          <div class="image-text"><?php echo $mem_uname; ?> ($8.75)<br>
            <span><?php echo date('jS M, Y (h:i a)', strtotime($pr_uptime)); ?></span></div>
        </div>
        <div id="myModal" class="modal"> <span class="close">&times;</span> <img class="modal-content" id="modalImg">
          <div id="caption"></div>
        </div>
        <?php } ?>
      </div>

Try using display : table

.inline-flex {
     width: 100%;
     display: table;
}

You need to set display: inline-block; float: left; to .image-container

.image-container {
    width: 163px;
    height: 120px;
    padding: 0px 0px 65px 0px;
    font-size: 12px;
    text-align: center;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    margin-right: 13px;
    display: inline-block;
    float: left;
}

.image-text {
    margin-top: 5px;
}
.image-text span {
    color: #ddd;
    font-size: 9px;
}
.inline-flex {
    width: 100%;
}

<div class="inline-flex">
   <div class="image-container"> <img class="myThumb" id="myImg" src="http://lorempixel.com/output/nature-q-c-200-200-3.jpg" alt="" width="160" height="100">
