You can link them, but not put the full picture in the thread. If you don't know how to do that, it's<div class="codeheader">Code: <a class="codeoperation" href="javascript:void(0);" onclick="return smfSelectText(this);">[Select]</a></div><pre style="margin: 0; padding: 0;"><code class="bbc_code">[url=link to the picture]link description[/url]. </code></pre>
