vBulletin CMS Widgets - Widget: display random image thumbnail from public albums

What it does ?
This widget displays a thumbnail image, taken randomly from any public albums and adds a "More..." link redirecting to albums.
Clicking on the thumbnail opens full sized picture in its current album.

Version history :
1.0: Initial release
1.1: Style can now be independant of template modification / Added option to display more than one thumbnail / Added option to define a custom size for the thumbnails.

Install instructions :
1- Go in to your AdminCP > vBulletin CMS > Widgets > Create new widget
2- Choose type 'PHP direct execution'
3- Give it a name (i.e: Random Picture)
4- Give it a description (i.e Random picture from public albums)
5- Save it
6- Configure it with the following code (copy/paste)

PHP Code:

// Display random images thumbnails taken from any public albums.
// Author : Sulquendi
// Version: 1.2

// -- Widget Configuration -- 
$use_vB_thumbnail_size     = false;
$use_custom_css         = false;
$twidth                 = 190;
$limit                    = 1;
$albums_list            = "";


// -- Nothing to configure below this line --
if ($use_custom_css){
    $pthumb     = 'class="pthumb"';
    $pcaption    = 'class="pcaption"';
    $pmore        = 'class="pmore"';
    $pstyle        = '';
}else{
    $pthumb     = 'style="text-align:center;"';
    $pcaption    = 'style="text-align:center;font-style:italic;font-family: Times, serif;margin-bottom:10px;"';
    $pmore        = 'style="text-align:right;display:block;"';
    $pstyle        = 'style="border: 1px solid black;padding:4px;background: white;"';
}
if ($albums_list!="") $sup_cond = "AND alb.albumid IN ($albums_list)"; else $sup_cond ="";
ob_start();
require_once(DIR . '/includes/functions_album.php');
require_once(DIR . '/includes/functions_user.php');
$pic_get = vB::$db->query_read("
    SELECT     alb.albumid, att.attachmentid, att.userid, att.caption, att.dateline, att.state, fdt.filesize, IF(fdt.thumbnail_filesize > 0, 1, 0) AS hasthumbnail, fdt.thumbnail_dateline, fdt.thumbnail_width, fdt.thumbnail_height, u.username

   LIMIT $limit");
  $output_bits = "";
  while($pic = vB::$db->fetch_array($pic_get))
  {
    $albuminfo = fetch_albuminfo($pic[albumid]);
    $picture = prepare_pictureinfo_thumb($pic, $albuminfo);
    if ($use_vB_thumbnail_size) $size = $picture[dimensions]; else $size = "width=$twidth";
    $output_bits .= "<div $pthumb><a href=\"album.php?{$vbulletin->session->vars['sessionurl']}albumid={$pic[albumid]}&attachmentid={$picture[attachmentid]}\"><img $pstyle src=\"attachment.php?{$vbulletin->session->vars['sessionurl']}attachmentid={$picture[attachmentid]}&thumb=1&d={$picture[thumbnail_dateline]}\" alt=\"{$picture[caption_preview]}\" $size /></a>";
    $output_bits .= "</div><div $pcaption>{$picture[caption_preview]} by {$pic[username]}</div>";
  }
$output_bits .= '<span '.$pmore.'><a href="album.php" alt="To the albums">More...</a></span>';
$output = $output_bits;
ob_end_clean(); 


7- There are 5 variables you can edit in this code, to configure the widget behavior :

PHP Code:

$use_vB_thumbnail_size     = false;
$use_custom_css         = false;
$twidth                 = 190;
$limit                = 2;
$albums_list            = "1,2,3"; 


$albums_list :
define a list of albums IDs (coma-separated list) to use, when taking a picture randomly.
You can also specify only one ID.
note: if you leave this variable empty, ALL public albums will be used.

$use_vB_thumbnail_size :
false = the widget will use $twidth to set up the width of the thumbnail.
true = default vBulletin thumbnail size will be used.

$twidth:
Width of a thumbnail (in pixel.)
will only be used if $use_vB_thumbnail_size is set to false.

$limit:
# of thumbnails you want to display in the widget.

$use_custom_css
false = the styling of widget elements will be performed inside the widget itself (using style="" html tag.)
true = the styling will be performed by CSS, thus a template needs to be manually edited : vbcms.css

.pthumb {
	text-align:center;
}
.pthumb img {
	border: 1px solid black;
	padding:4px;
	background: white;
}
.pcaption {
	text-align:center;
	font-style:italic;
	font-family: "Times New Roman", Times, serif;
	margin-bottom:10px;
}
.pmore {
	text-align:right;
	display:block;
}

8- Your widget is ready to be added to your CMS with AdminCP > vBulletin CMS > Widgets > Layout Manager

hmmm, when not logged in the thumbnails are just white boxes - any way to make it so that thumbnails show on when not logged in. Have it on homepage of www.thewoollybacks.co.uk

[orangefive]

or.... is it possible to create a user account with complex password and specify that account in the code to only be used for displaying the images?

hallo,
great tool but the pictures do not move

I was being a bit thick - changed usergroup permissions on not logged in to be able to view public albums and now works like a charm at www.thewoollybacks.co.uk

I would like to figure out how to stack the images horizontally. I was playing with the CSS and was able to get them to stack with float:left, but the widget content area would not expand with the series.

I tried to add in a DIV to consolidated the widget into one box, but I lack the skills to add that int he PHP code. I played with this for 4 hours.

Example: http://fordstnation.com/content.php?120-gallery

Maybe there is a quick fix to the .cms_widget_content class in the CSS?

The above works a treat, also set $use_vB_thumbnail_size to false!

If you want to remove the 'by [username]' from the caption, then just find and remove

by {$pic[username]}

My board is 4.1.7 and this appears to work fine!

I got the code to work with horizontal.

Minor HTML edit in the php output, and some CSS work did the trick. This is a great script, suites my needs well.
