Use the action attribute.

<h:commandButton image="image.gif" action="#{myBean.action}" />

Create a h:commandButton and hide it using CSS display: none; and then in the onclick of the image you can invoke the hidden commandButton using Javascript: document.getElementById('formId:buttonId').click().

But I recommend you to gently use the h:commandButton with the image.

BalusC,

It seems to me that the following is more straightforward, but perhaps there is some gotcha I am not aware of. Use a commandButton along with the image and an onclick handler. Then the JavaScript runs and the form is submitted afterwards. It only gets tricky if he needs to conditionally submit the form, it which case he needs to swallow the mouse click event.

True =)

But as far I understood, he want to use the following construction:<h:graphicImage value="image.gif" onclick="submitFormSomehow();" />

, so I was suggesting him to use h:commandButton with an image instead. He also didn't mention about some Javascript requirements, so an onclick is also not needed.
