singlepic-caption template

I looked for a convenient way to place captions beneath floated images but I had no luck searching. Here is my solution which I hope might help others.

First, I needed to know, within a template, whether the image was floated left or right, so I modified nggfunctions.php. For version 1.6.2 this change occurs on or about line 808:

insert into line: , ‘float’ => $float

resulting in

$out = nggGallery::capture ( $filename, array ('image' => $picture , 'meta' => $meta, 'exif' => $exif, 'iptc' => $iptc, 'xmp' => $xmp, 'db' => $db, 'float' => $float) );

Now you’ll have access to a new variable named $float inside your template. I named my template: singlepic-caption

Within the views folder create a file named singlepic-caption.php containing:

<?php
/**
Template Page for the single pic with a caption - additions by Mark Levine www.istarnet.com

Follow variables are useable :

	$image : Contain all about the image
	$meta  : Contain the raw Meta data from the image
	$exif  : Contain the clean up Exif data from file
	$iptc  : Contain the clean up IPTC data from file
	$xmp   : Contain the clean up XMP data  from file
	$db    : Contain the clean up META data from the database (should be imported during upload)
	$float : Contains the class to position the caption, eg. ngg-right

Please note : A Image resize or watermarking operation will remove all meta information, exif will in this case loaded from database 

 You can check the content when you insert the tag <?php var_dump($variable) ?>
 If you would like to show the timestamp of the image ,you can use <?php echo $exif['created_timestamp'] ?>
**/

if (!defined ('ABSPATH')) die ('No direct access allowed');

if (!empty ($image)) :
	echo '<p class="ngg-singlepic-caption'.$float.'" style="width:'.(8+$image->width).'px;';
	// insert a margin style if the image is floated
	switch($float) {
	case ' ngg-left':
		echo 'margin:0 10px 0 0';
		break;
	case ' ngg-right':
		echo 'margin:0 0 0 10px;';
		break;
	default:
		break;
	}
	echo '">';

	echo '<a href="'.$image->imageURL.'" title="'.$image->linktitle.'" '.$image->thumbcode.' >';
	echo '<img';
	echo ' src="'.$image->thumbnailURL.'"';
	echo ' alt="'.$image->alttext.'"';
	echo ' title="'.$image->alttext.'"';
	echo ' />';
	echo '</a>';
	if (!empty ($image->description)) :
		echo $image->description;
	endif;
	echo '</p>';
endif;

Now you can use [ singlepic id=N template=caption float=right ]
