    Hi, welcome to the monastery.

    Tk::Photo doesn't handle downloading images from a URL. However combined with a pair of additional modules, you can do it yourself:

    use Tk; use Tk::Photo; use Tk::JPEG; use LWP::Simple; use MIME::Base64 qw(encode_base64); my $mw=new MainWindow; my $data = encode_base64 get(''); my $shot=$mw->Photo(-data=>$data,-format=>'jpeg'); $mw->Label(-image=>$shot)->pack; MainLoop;

    Can TK make the http connection and grab the actual file? I ask in ignorance.

      Uhhmm... i dont think so but i am using Net::FTP to grab the actual image file but i was trying to seek tweaks! for this statement

        Well, that was sorta' crucial information for those who might want to help, wasn't it?

        Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
        1. code
        2. verbatim error and/or warning messages
        3. a coherent explanation of what "doesn't work actually means.
