General Support: at Post a comment, how can i disable E-mail,image verification?

Me too. You need to edit the comments.php in your themes/yourtheme/ directory. I myself use the 'softer' theme (can be found on the forums or google). Look for this code:

<form action="' . $config["gallery_url"] . 'plog-comment.php" method="post" id="commentform">
<p>
<input type="text" name="author" id="author" class="textarea" value="" size="28" tabindex="1" />
<label for="author">Name</label> (required) <input type="hidden" name="comment_post_ID" value="40" />
<input type="hidden" name="parent" value="'.plogger_get_picture_id().'" />
</p>
<p>
<input type="text" name="email" id="email" value="" size="28" tabindex="2" />
<label for="email">E-mail</label> (required, but not publicly displayed)
</p>
<p>
<input type="text" name="url" id="url" value="" size="28" tabindex="3" />
<label for="url">Your Website (optional)</label>
</p>
<p>
<label for="comment">Your Comment</label>
<br /><textarea name="comment" id="comment" cols="70" rows="4" tabindex="4"></textarea>
</p>
<p class="inputbuttonp">
<input class="submit" name="submit" type="submit" tabindex="5" value="Post Comment" />
</p>
</form>';

And start hacking away. I changed it into

<form action="' . $config["gallery_url"] . 'plog-comment.php" method="post" id="commentform">
<p>
<input type="text" name="author" id="author" class="textarea" value="" size="28" tabindex="1" />
<label for="author">Je naam</label> (verplicht) <input type="hidden" name="comment_post_ID" value="40" />
<input type="hidden" name="parent" value="'.plogger_get_picture_id().'" />

<input type="hidden" name="email" id="email" value="anonymous@user.com" size="28" tabindex="2" />
<p>
<label for="comment">Je reactie</label>
<br /><textarea name="comment" id="comment" cols="70" rows="4" tabindex="4"></textarea>
</p>
<p class="inputbuttonp">
<input class="submit2" name="submit" type="submit" tabindex="5" value="Plaats reactie" />
</p>
</form>';

So now the form only requires a name and the comment. Note the hidden input for the e-mail adress, which is required by plogger, and now defaults to 'anonymous@user.com' for every comment.
