in reply to remove a random variable from an array

do this 
for($i=1; $i<=$a; $i++){
       $randomelement = int(rand @thumbs);
       print "<img src=\"$picture_directory/$thumbs[$randomelement]\">
+$picture_directory/$thumbs[$randomelement]<br>";
       splice(@thumbs, $randomelement,1);
}

you need the int() since rand returns a decimal, and you were trying to splice out the value of the array index, not the actual index number...

    @arr = qw(zero one two three four five);
print "$_: $arr[$_]\n" for(3, 3.1415926);
