Images on a MediaWiki wiki will by default, link to the description page
Here is a work around that when you click an image it will link to an ariticle

[[Image:Wiki.png|50px|link=MediaWiki]]

Note: The code above will work in mediawiki version 1.14 and above only
——————————————————————————————————-
Here is the workaround for older versions
Edit the Common.css

.imagelink_somename a {
  width:100px;
  height:100px;
  display:block;
  text-decoration:none;
  background-image: url("http://fullurltoimage")
}

In your wiki code:

<div class="imagelink_somename">[[Some link|&nbsp;]]</div>

——————————————————————————————————–
Or try the quick way

<div style="position: relative; width: {{{width}}}; height: {{{height}}}; overflow: hidden;">
<div style="position: absolute; top: 0px; left: 0px; font-size: 100px; overflow: hidden; line-height: 100px; z-index: 3;">[[{{{link}}}|&nbsp;&nbsp;&nbsp;]]</div>
<div style="position: absolute; top: 0px; left: 0px; z-index: 2;">[[Image:{{{image}}}|{{{width}}}|{{{link}}}]]</div>
</div>
