I've tried this on my local wiki:

[[(% class="myclass" %)[[image:XWikiLogo.png||width="25" 
height="25"]]>>http://xwiki.org]]

And it generates:

<p><span class="wikiexternallink"><a href="http://xwiki.org";><span 
class="myclass"><img 
src="http://localhost:8080/xwiki/bin/download/Sandbox/WebHome/XWikiLogo.png?width=25&amp;height=25";
 width="25" height="25" alt="XWikiLogo.png"/></span></a></span></p> 

So as you can see it does generate a <span>.

Now if you want the params to apply to the img tag you need to pass them as 
image params:

[[[[image:XWikiLogo.png||width="25" height="25" 
class="myclass"]]>>http://xwiki.org]]

which generates:

<p><span class="wikiexternallink"><a href="http://xwiki.org";><img 
src="http://localhost:8080/xwiki/bin/download/Sandbox/WebHome/XWikiLogo.png?width=25&amp;height=25";
 width="25" height="25" class="myclass" alt="XWikiLogo.png"/></a></span></p>

Hope it's clear.

Thanks
