Gossamer Forum: Products: Gossamer Links: Development, Plugins and Globals: Quite cool global...

Just thought I would share this new global I just wrote =)

Basically, if you are using the service from Thumbshots.ORG, then you can use this global, to check if an image exists for the current URL ... and if it doesn't, then it will give back the image code, with just the root URL (i.e if an image wasn't found for http://www.gossamer-threads.com/scripts/ , then it would try to see if one existed for http://www.gossamer-threads.com/).

Simply call with <%global_name%> (in link.html, or detailed.html);

Code:
sub { 
  my $tags = shift; 
  my $url = $tags->{URL}; 
  use LWP::Simple; 
  if (get("http://open.thumbshots.org/image.pxf?url=$url")) { 
    return qq|<img src="http://open.thumbshots.org/image.pxf?url=$url" border="0" onload="if (this.width>50) this.border=1; this.alt='Preview by Thumbshots.org';">|; 
  } else { 
    my @cut = split /\//, $url; 
    my $rooturl = "http://" . $cut[2]; 
    return qq|<img src="http://open.thumbshots.org/image.pxf?url=$rooturl" border="0" onload="if (this.width>50) this.border=1; this.alt='Preview by Thumbshots.org';">|; 
  } 
}

Enjoy

Cheers
