It is not possible to move the position of the Social Media icons via the interface but you could try the following:
(1) Open the 'showkase/_themes/base/pagetypes/basetheme.tpl' file in a plain text editor.
(2) Move lines 179-189 inclusive (the following block of code) to line 165 (which is currently blank) immediately below the closing </nav> tag.
<div class="socmedia">
<a href="{$facebookLink}" title="facebook"><span class="icon-facebook2"></span></a>
<a href="{$flickrLink}" title="flickr"><span class="icon-flickr3"></span></a>
<a href="{$googleplusLink}" title="Google+"><span class="icon-google-plus2"></span></a>
<a href="{$instagramLink}" title="Instagram"><span class="icon-instagram"></span></a>
<a href="{$linkedinLink}" title="LinkedIn"><span class="icon-linkedin"></span></a>
<a href="{$pinterestLink}" title="Pinterest"><span class="icon-pinterest2"></span></a>
<a href="{$tumblrLink}" title="Tumblr"><span class="icon-tumblr2"></span></a>
<a href="{$twitterLink}" title="Twitter"><span class="icon-twitter2"></span></a>
<a href="{$vimeoLink}" title="Vimeo"><span class="icon-vimeo2"></span></a>
</div>
(3) Open the 'showkase/_themes/kosel/css/custom.css' file in a plain text editor.
(4) As Showkase expects the Social Media icons to be in the footer, the CSS rule which usually sets the icon size will no longer be used. Add the following CSS code to the 'showkase/_themes/kosel/css/custom.css' file to solve this problem and to align the icons to the right.
.socmedia {
clear: both;
text-align: right;
}
.socmedia a {
font-size: 1.5em;
}
(5) Republish your site after making the changes above.
Please note that as Showkase was not designed with this layout in mind, you might encounter other unforeseen issues which you might need to tackle (perhaps with additional CSS rules).
Also, the line numbers above refer to the most recent version of Showkase (v1.4.2).
I hope this helps.
