Very nice and easy to insert pictures with the slimbox effect into joomla articles.

Hint for gettintg spaces between images:
edit slimbox.php, line 123

$withthis .= '';

After the you can put your amount of spaces( ) you like.

After that line you can insert the follwing for a choosen amount of pictures per line:

if ( (($j+1)%NUMBER OF PICURES PER LINE) == 0){
$withthis .= '';
}
