Question

I have this simple JSF button:

//Question Dialog
function deletedialog(button, a){      
    $("<div />", {
        text: a
    }).dialog({        
        width: 600,
        buttons: {
            "Ok": function() { 
                $("#form\\:deleterow").click();
                //  $('input[id$="deleterow"]').click();               
                $(this).dialog("close");
                button.value = "Processing...";
                button.disabled = true;                  
            }, 
            "Cancel": function(event) { 
                $(this).dialog("close");
                event.preventDefault();
                button.value = "Delete";
                button.disabled = false;
            } 
        }
    });         
}


                    <!-- hidden button -->
                    <h:commandButton id="deleterow" value="HiddenDelete" action="#{AccountsController.deleteSelectedIDs}" style="display:none">
                        <f:ajax render="@form"></f:ajax>
                    </h:commandButton>
                    <!-- the delete button -->
                    <h:button onclick="deletedialog(this, 'Do you want to delete the selected rows?'); return false;" >
                        <h:graphicImage name="small-hover.png" library="images" title="Delete" />
                    </h:button>    

I want to create png image which will be the visual body of the button. The only thing that I will change will be the title of the button which I will set every time using the value attribute of the button. Is this possible? Now when I load the JSF page I see only empty button without label.

P.S 1 I get this result:

Use a command link that will wrap your image:

<script type="text/javascript">
    function deletedialog(button, a) {
        $("<div />", {
            text: a
        }).dialog({        
            width: 600,
            buttons: {
                "Ok": function() { 
                    //$("#form\\:deleterow").click();
                    //using the hidden button click
                    document.getElementById('myForm:deleterow').click();
                    //  $('input[id$="deleterow"]').click();               
                    $(this).dialog("close");
                    button.value = "Processing...";
                    button.disabled = true;                  
                }, 
                "Cancel": function(event) { 
                    $(this).dialog("close");
                    event.preventDefault();
                    button.value = "Delete";
                    button.disabled = false;
                }
            }
        });
    }
</script>

<h:form id="myForm">
    <h:commandLink onclick="deletedialog(this, 'Do you want to delete the selected rows?')) return false;">
        <h:graphicImage name="small-hover.png" library="images"
            title="#{someBean.imageTitle}" />
    </h:commandLink>
    <h:commandButton id="deleterow" value="HiddenDelete" action="#{AccountsController.deleteSelectedIDs}" style="display:none">
        <f:ajax render="@form" />
    </h:commandButton>
</h:form>

Also, there is a good example of <h:graphicImage/> in mkyong site.

Based on your comments, it looks like you want to have a button with an icon. Also, the real action is performed by your hidden <h:commandButton>. so I recommend you to read this answer:

• HTML / CSS How to add image icon to input type=“button”?

Your code would be like this:

<h:commandButton id="deleterow" value="HiddenDelete" action="#{AccountsController.deleteSelectedIDs}" style="display:none">
    <f:ajax render="@form" />
</h:commandButton>
<button type="submit" onclick="deletedialog(this, 'Do you want to delete the selected rows?')) return false;"><img src="resources/images/small-hover.png" /> Delete</button>

Yes, you can mix basic HTML with JSF code, but read the link warning about this implementation on IE 6 browser clients.
