not adding space

Normally when spacing out something like this, you want to do all that with css.

So I would suggest that you clean up the code so that it looks like:

<ul class="storefront">
<li><a href="">first image</li>
<li><a href="">second image</li>
etc..... with more <li> for the other images

</ul>

This in the css you can do something like:

ul.storefront {list-style:none;}

ul.storefront li {padding:0 30px 30px 0;}
