Apply a float:left on .custimage

.custimage{
   position:relative;
   margin-top: 15px;
   margin-left: 15px;
   height: 170px;
   width: 130px;
   background-color: #999;
   text-align:left;
   float: left;  // float all cust images to the left so they stack up against each other

Answer 2

Add float: left to .custimage .

Answer 3

two ways:

first: add float:left to your .custimage

second: instead of float, add display:inline-block to your .custimage.

The second one does not work in older Browsers, but is way more cleaner than let all float around.
