hi i'm still learning some basics of php, and now i'm trying to modify codes.. and follow tutorials
after following a tutorial i made this multi-uploader which uploads images and thumbnails
but there's a little thing with it, it changes the image name to random name, and i want it to keep the original file name..

i did tried (alot actually) and i found the function that creates the random name, but it has a variables within in it, and i did tried to change these variables, but it seems to be out of my limits for now.. because they are linked with other more complicated lines ..

so i wish if you could help me and comment what did you do so that i learn..

Line 69:

 $image_random_name= random_name(15).".".$extension ;

try this:

 $image_random_name = $_FILES['image']['name'][$i];

or you can use $filename which is declared in line 58 and change line 70 to:

$copy = @move_uploaded_file($_FILES['image']['tmp_name'][$i], $images_location.$filename);

Bye!
