Add these two methods to _itemlist.class.php, then you can do

$params['image_link_to'] => $MainList->get_prev_item_url();

/**

 *
 * Note: Each item has an unique permalink at any given time.
 * Some admin settings may however change the permalinks for previous items.
 * Note: This actually only returns the URL, to get a real link, use {@link ItemList::prev_item_link()}
 *
 * @param string single, archive, subchap
 * @param string base url to use
 * @param string glue between url params
 */
function get_prev_item_url( $permalink_type = '', $blogurl = '', $glue = '&' )
{
	/**
	 * @var Item
	 */
	$prev_Item = & $this->get_prevnext_Item( 'prev' );

	if( !is_null($prev_Item) )
	{
		return $prev_Item->get_permanent_url( $permalink_type, $blogurl, $glue );
	}
	return '';
}

function get_next_item_url( $permalink_type = '', $blogurl = '', $glue = '&' )
{

	if( !is_null($next_Item) )

	return '';
}

ps. I just added these methods to v5

Great ! Havent tried yet, have to upgrade first, probasbly tonight.I ll just use the cvs package u sent me the other day.

How about "looping" ?

How about "looping" ?

It's not easy :(
Basically when you check for 'prev' and see that there's no previous (older) post, you run the second check for the newest 'next' and get it's URL

See the get_prevnext_Item() method in _itemlist.class.php

So i put this in _item.block.inc.php :

	<?php
	// Default params:
$params = array_merge( array(
				'before' =>              '<div class="bImages">',
				'before_image' =>        '<div class="image_block">',
				'before_image_legend' => '<div class="image_legend">',
				'after_image_legend' =>  '</div>',
		//		'after_image' =>         '<div class="fblikke over"><fb:like href='.$baseurl.'index.php?p='.$Item->ID().'" send="true" layout="box_count" width="80" show_faces="true" font="verdana"></fb:like></div></div>',
				'after_image' =>         '</div>',
				'after' =>               '</div>',
				'image_size' =>          'fit-720x500',
    ), $params ); 
	
;
$params['image_link_to'] = $MainList->get_prev_item_url();  

and i got:

Fatal error: Call to undefined method ItemList2::get_prev_item_url() in /home/..../public_html/skins/photoblog/_item_block.inc.php on line 50

Note that i changed => to =, otherwise i would just get syntax error:

Parse error: syntax error, unexpected T_DOUBLE_ARROW in /home/tilqi/public_html/skins/photoblog/_item_block.inc.php on line 51

(on single post pages) Also got:

Fatal error: Cannot redeclare get_prev_item_url() (previously declared in /home/.../public_html/inc/items/model/_itemlist.class.php:709) in /home/.../public_html/inc/items/model/_itemlist.class.php on line 709

First disable colorbox effect in skin. Then make sure you applied appropriate changes to _itemlist.class.php
Also you should get "next" item instead of previous.

You need to trick Photoblog skin to prev/next items even if $disp != 'single'

Make the code in your skin look the same

global $Item, $MainList;
$MainList->single_post = true;

          $params = array_merge( array(
                'before' =>              '<div class="bImages">',
                'before_image' =>        '<div class="image_block">',
                'before_image_legend' => '<div class="image_legend">',
                'after_image_legend' =>  '</div>',
        //        'after_image' =>         '<div class="fblikke over"><fb:like href='.$baseurl.'index.php?p='.$Item->ID().'" send="true" layout="box_count" width="80" show_faces="true" font="verdana"></fb:like></div></div>',

                'image_link_to' => $MainList->get_next_item_url(),
    ), $params );

nope, didnt work again... no errors, but no image shown both in single or post mode.

Just PM me your FTP pass ;)

Any idea how i can display homepage in single mode with the latest post ? I dont want a page of posts.Single mode is better for photoblog, it displays a single post already

Put this above skin_init($disp) in index.main.php and posts.main.php

if( is_default_page() )
{
    $disp = 'single';
    $posts = 1;
}

Untested, of course :)

nope..that didnt work.
it's basically the same thing i know, but i also tried doing below,

if( is_default_page() )
{
$disp = 'home';
}

skin_include( '$disp$', array(
'disp_home' => '_single.main.php',
) );

That didnt work too.Cant trick it
