Hi
I modified the script a little bit to suit my needs,
but when i call the script 2 times on the same page
my page crashes,
I use the following call:
[!PhotoGallery? &folder=`inbouwkasten_wilrijk` &image_link_rel=`inbouwkast` &title=`Inbouwkasten - Wilrijk` &thumbnail=`inbouwkast.jpg` !]
What am i doing wrong, and how can i modify tje script that this works fine
<?php
/**
* @name PhotoGallery
* @author Dave Child <[email protected]>
* @license GPLv3
* @version 0.1
*
* This snippet returns a photo gallery with subfolders. Shows
* thumbnails of images and links to full size. Works with most
* common lightbox clones. Designed and tested with prettyPhoto
* (a jQuery lightbox clone: http://tinyurl.com/dkuwya ).
*
* Shows JPG, JPEG, GIF and PNG images in the target folder.
* Image title is taken from the image name.
*
* &folder=`foldername`
* Folder to display. Not optional. Must be within assets/images/
*
* &width=`60` - Optional
* Thumbnail width. Defaults to 60. TinyMCE thumbnails are 96
* by 96 by default. Probably best not to use thumbnails larger
* than that unless you’ve set TinyMCE to use bigger dimensions.
*
* &list_class=`gallery` - Optional
* Class to add to the ul containing the photos. Defaults to
* blank.
*
* &image_link_rel=`prettyPhoto` - Optional
* Most galleries use a rel on the link to control the popup.
* Defaults to blank.
*
* &subfolder_list_title=`Sub-Galleries` - Optional
* Title for the subfolders list. Uses an h2. If left blank,
* returns no title and no h2.
*
* &subfolder_list=`on` - Optional
* Return the subfolders list. "on" or "off".
*
* &image_list_title=`Photos` - Optional
* Title for the images list. Uses an h2. If left blank,
* returns no title and no h2.
*
* &image_list=`on` - Optional
* Return the image list. "on" or "off".
