[Plugin: Live Comment Preview] Gravatars shown in preview even if turned off in blog settings

Got it to work. Here are the changes, if you’d like to incorporate them:

line 35:

// Customize this string if you want to modify the preview output
	// %1 - author's name (as hyperlink if available)
	// %2 - comment text
	// %3 - gravatar image url
	$previewFormat = '
		<ol class="commentlist" style="clear: both; margin-top: 3em;">
			<li id="comment-preview" class="alt" style="overflow: hidden;">';
	if (get_option('show_avatars') != '0')
		$previewFormat .= '<img src="%3" alt="" class="avatar avatar-' . $gravatar_size . '" width="' . $gravatar_size . '" height="' . $gravatar_size . '"/>';
	$previewFormat .= '<cite>%1</cite> Says:
				<br />
				%2
			</li>
		</ol>';

around line 200:

if (get_option('show_avatars') != '0') $previewFormat = str_replace("%3", "' + gravatar + '", $previewFormat);

n/m, that worked in testing but removed the comment text in production.

get_avatar does have the check built in. Look at the code in the default theme:
<?php echo get_avatar( $comment, 32 ); ?>

That’s all it takes in a theme.

Live Comment Preview, on the other hand, is *live*. It’s generated via some other means, not via the PHP code.

I know. I just can’t seem to make it work. For now I’ve disabled the avatar in the CSS: #comment-preview img.avatar { display: none; }
