I added I18n support to my qPloneCaptchas, I think this would be a good idea even if there is only one line visible to the normal user (had problem attaching files).

In captcha_widget.pt replace:

     <label for="key">Enter the word below</label>
     <span class="fieldRequired" title="Required">(Required)</span><br />

With:

     <label for="key" i18n:translate="enter_word">Enter word</label>



     <span class="fieldRequired" title="Required"

           i18n:attributes="title title_required;"

           i18n:translate="label_required">(Required)</span><br />

Add I18n folder in qPloneCaptchas product folder

Add translation files.
