I added some code to the List-all-themes plugin so that it will only show available themes and won't show the home theme. I hope it is okay if I post this? Keep in mind I know almost nothing about php...

After:
$themes = get_themes();
add this:

$allowed_themes = get_site_option( "allowed_themes" );
if( $allowed_themes == false ) {
$allowed_themes = array();
}
$blog_allowed_themes = get_option( "allowed_themes" );

reset( $themes );
while( list( $key, $val ) = each( $themes ) ) {
if( isset( $allowed_themes[ $key ] ) == false ) {
unset( $themes[ $key ] );
}
}
reset( $themes );


after:
$screenshot = $themes[$theme_name]['Screenshot'];
add this:
if ( $stylesheet_dir == "wp-content/themes/home" ) continue;

Okay, that last bit is a total hack but nothing else I tried worked.

here it is in action: http://screenwriters.la/theme-directory/

I also added a bit so it would show thumbnails:
<img width="300px" height="220px" src="<?php echo get_option('siteurl') . '/' . $stylesheet_dir . '/' . $screenshot; ?>" alt="<?php echo $title ?>" />

One thing you may want to do, and I suggest this because folks raised heck on my support forum is a lot of those screencaps are very large *.pngs, some of them 150kb+.

I went though and resaved each and everyone of them as *.jpgs of less than 15kb. Lots of folks thanked me even though it took most of an afternoon to do it.

how do you get the themes to list 3 to a row?

dig...

how to list 3 in one row?

It will automatically make 3 in a row if the width of your box is wide enough. You may need to play with it to get it to work. For mine, I made a theme.php template and tweaked it. I had a lot of help from Ovidiu in this thread:

Oh, and posh ... works beautifully - but I did notice that if you have a theme activated for just one blog, it's on the list. The theme I use for my main blog is only activated for that one, yet it shows up in the list. Other than that, it took all the other ones out! Beautimous! ;)
