Hi All

I apreciate if anybody help me in this little problem... I just want to store an image from a url in a variable, but sometimes anything go wrong, and the routine can't open the url...so i create this code: 

$size = 0;
use LWP::Simple;

while ($size == 0) {
my $data2 = LWP::Simple::get $site;
my $size = length($data2);
print "$size\n";
}

My wish is that, when the image are really stored in variable $data, the loop stop, and the programe continue... but my problem is that the loop is continually looping..

Somebody can help me?
