taxonomy with image field is not translating
I tried wolverine's answer but it didn't worked for me, it caused error "#build_id not defined" so I changed it a little, I don't know if it's right solution but it worked for me.

Add only this code in your module:

function MYMODULE_form_alter(&amp;$form, &amp;$form_state, $form_id) {
    if (($form_id == 'taxonomy_form_term') &amp;&amp; (!isset($form_state['triggering_element']) || $form_state['triggering_element']['#id'] != 'edit-delete')) {
        if (!isset($form_state['storage']['rebuilding'])) {
            $form_state['storage']['rebuilding'] = TRUE;

        } else {
            $form_state['no_cache'] = TRUE;
        }
    }
}


Hope it's helpful for someone.
