I did a quick search, but didn't quite find anything that was sufficiently close to be an answer

I'm trying to use File::Find to find image files, so I can randomly change my wallpaper. I know; it's a silly task ⌣. My problem is that I have a bunch of image files on a flash drive, and File::Find won't follow a symbolic link to the contents of the flash drive. I suspect it's because File::Find, even when $File::Find::follow is set won't recurse into a different file system.

I'm using Fedora 21, Perl v5.18.4, File::Find version 1.23. 

sub image_search {

    my $name = $File::Find::name;
    my $dir  = $File::Find::dir;

    my @globbed;
    my @temp;

    my $images = '(png$)|(jpg$)|(gif$)|(jpeg$)';

    if (-l $name) {

        print "processing link named $name\n";
        @globbed = glob("$name/*");
    }
    else {
        print "processing directory named $dir\n";
        @globbed = glob("$dir/*");
    }

    if (@globbed) {
        @globbed = grep {m/$images/i} @globbed;

        $image_list{$dir} = [@globbed];
    }
} ## end sub image_search
