Here's my latest attempt. It shows the exif info without a toggle, removes gray box around the label, and removes "Image Info" text.

I bailed out of the skeleton theme, and went with one of the officially supported ones just to keep it simple. In my case, I used a duplicate of "default".
I modified one of the core files, which bothers me a bit, but here are the changes I made:
=====================================================
zp-core/template-functions.php
line 2282
commented out
if (is_null($title)) {
$title = gettext('Image Info');
}
line 2410
commented out
<div<?php echo $id . $class; ?>>
line 2415
changed this
echo "<tr><td class=\"label\">$label:</td><td class=\"value\">";
to this
echo "<tr><td>$label:</td><td class=\"value\">";
============================================================
themes/defaultcopy/image.php
line 93:
changed this
printImageMetadata(NULL, 'colorbox');
to this:
printImageMetadata(NULL, '');
====================================================
I think I got all the changes here. If it doesn't work, let me know, and I'll recheck to see if I missed a step.
If anyone smarter than me sees a mistake, don't hesitate to correct this.
