<form method="post" action={"/content/action"|ezurl} name="newPhoto">
    <input type="hidden" name="NodeID" value="1180" />
    <input type="hidden"  name="ClassID" value="5" />

I solved problem in this way - i made hidden field instead of button. This works:

<form method="post" action={"/content/action"|ezurl} name="newPhoto">
    <input type="hidden" name="NodeID" value="1180" />
    <input type="hidden"  name="ClassID" value="5" />        
<input type="hidden" name="NewButton" value="{'Create here'|i18n('design/standard/node/view')}" />
    <a href="#" onclick="document.forms.newPhoto.submit()">Add Photo</a>
</form>

{set-block scope=root variable=cache_ttl}0{/set-block}

I saw you found a solution, but to answer to your initial question:

everytime you have a from that perform an action that change the state of your system (add delete or modify), the W3C ask to use a post action (not a get, ie. not a link). This avoids, for instance, robots of the search engines creating zillions of drafts while indexing your site.
