Vigorous Hive

Sorry about that, we have troubles connection to wp ropository this days due to local internet. Now zip should be ok.
Can you try it?

Thanks for your patience.

I can add a field for custom css rules, if you want, but i do not think it is good idea.

Image position is up to your theme. Vihv Menu is backend plugin. Ordinary menu item has html code like this:

<a href="http://me/wpsandbox/?page_id=709">Services</a>

and vihv menu replaces it with this

<a href="http://me/wpsandbox/?page_id=709">
  <img alt="Home" src="http://www.vihv.org/images/shortcut.png">
  <span>Services</span>
</a>

As you can see, you have 2 separate html tags for icon and for menu item title. That’s enough to control everything. For example you can change default layout
[icon] [title]
to
[title] [icon]
with simple css rule like this

.menu a img {
  float: right;

}

If images are far from menu on your theme it means that some of css rules in your theme apply to menu images. You can change active theme for a second and see the difference. And you can use rightclick->inspect element (in chrome and opera) to find that naughty rule.

Nora, will menu item title be good as alt tag for menu icon? I can create separate field for this, but it looks like duplication of the same data for me.
