Displaying command button with image only

Question

I am trying to display a button with image only on my page but all I see is the button with ^. Following is the code for my button:

<p:commandButton onclick="lineSearch.show();" image="backgroung-image:url(/images/title_logo.jpg)"/> 
<p:dialog header="Modal Dialog" widgetVar="lineSearch" modal="true" onCloseUpdate="lineIdField" showEffect="scale" hideEffect="explode">  
    <ui:include src="lineSearch.xhtml"/>
</p:dialog>

The image does exist in the images folder. The button is rendered as following in the page:

<button id="j_idt23:j_idt27" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-icon-only" type="submit" onclick="lineSearch.show();;PrimeFaces.ab({formId:'j_idt23',source:'j_idt23:j_idt27',process:'@all'});return false;" name="j_idt23:j_idt27" role="button" aria-disabled="false">
    <span class="ui-button-icon-primary ui-icon backgroung-image:url(/images/title_logo.jpg)"></span>
    <span class="ui-button-text">ui-button</span>
</button>
<script type="text/javascript">
    widget_j_idt23_j_idt27 = new PrimeFaces.widget.CommandButton('j_idt23:j_idt27', {text:false,icons:{primary:'backgroung-image:url(/images/title_logo.jpg)'}});
</script>

Thanks!!!

The image attribute has to refer a CSS class name, not a plain CSS property. So, this should do:

<p:commandButton image="someCssClassName" /> 

with the following in your CSS:

.someCssClassName {
    background-image: url(images/title_logo.jpg)
}

Please note that I fixed the major typo in property name and also removed the leading slash from the image URL, it would otherwise be resolved relative to the site's domain root; the above expects the title_logo.jpg to be inside an /image folder which in turn is in the folder where the CSS file resides.

However, this one is less clumsy, I think:

<p:commandLink action="#{bean.submit}">
    <h:graphicImage name="images/title_logo.jpg" />
</p:commandLink>
