[QUOTE][u]Quote by: Anonymous[/u][p]It always shows me "no albums found" thing..i have 3 albums created and everything configured right..what could be the problem??
Here is the code im talking about:

/**
* This is the function that returns a random image from the Gallery
*
* NOTE: this does not like albums with no pictures in it!
*
*/
function phpblock_gallery()
{
    global $_CONF;

// Location of the Gallery album directory
    $path_gallery_albums = $_CONF['path'] . 'screenshots/gallery';

// URL to the gallery
    $gallery_url = $_CONF['site_url'] . '/screenshots';

// URL to album directory
    $gallery_album_url = $_CONF['site_url'] . '/screenshots/gallery';

// Bail if we have a bad path
    if (!is_dir($path_gallery_albums)) return "invalid directory";

// Open album directory
    $fd = opendir($path_gallery_albums);
    $albums = array();
    $index = 1;

// Load all albums into an arrray.  NOTE: this should be modified at
    // some point to ignore empty albums!!!!!!
    while (($f = @readdir($fd)) == TRUE) {
        if (is_dir($path_gallery_albums . $f) && !ereg('hidden',$f) && $f <> '.' && $f <> '..' && $f <> 'CVS' && ($f <> '.users')) {
            clearstatcache();
            $albums[$index] = $f;
            $index++;
        }
    }
    closedir($fd);

if (count($albums) == 0) return $retval .= "no albums found";

// Randomly select an album from the array
    mt_srand((double)microtime()*1000000);
    $indexr = (mt_rand(1, count($albums)));
    $rand_album = $albums[$indexr];

// Now get a random picture from this album
    $thepic = phpblock_random_files($path_gallery_albums . $rand_album);
    $pos = strpos($thepic, '.');
    $pic_prefix = substr($thepic, 0, $pos);

// build HTML output and return it
    $retval .= "<div align=center> <a href="";
    $retval .= $gallery_url . '/view_photo.php?set_albumName=' . $rand_album . '&id=' . $pic_prefix;
    $retval .= "">";
    $retval .= "<img border=0 src="";
    $retval .= $gallery_album_url . '/' . $rand_album . '/' . $thepic;
    $retval .= "">";
    $retval .= "</a> <br></div>n";

return $retval;

}

    $index = 1;
