This is important couse if somebody upload a picture a number is generated, but how do i write the image path for the picture if i don't no what number's been generated?
Thank you in advance.

Why not use "microtime"?

hehehe.... this is portuguese, not spanish.

Try to use this code:

?php

$time = microtime();
$strsp = " "; // string delimiter.
list ($dt, $t) = explode( $strsp, $time );

/*
$dt -> variable assigned by the user to represent the fractionary
decimal part of $time

$t -> variable assigned for by user to represent the integer decimal
part of $time
*/

echo " \$t = " . $t . " s<br /><br />";
echo "\$dt = " . $dt . " s<br /><br />";

echo "\$t + \$dt = ";
echo $t + $dt . " s";

/*
For each new execution of this script, a bigger value than the previous
$time is generated.
You can use the integer decimal part ($t) to generate a new unique value
*/

?>
