everytime i get the following error

Warning: move_uploaded_file(/upload/banner.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in E:\xampp\htdocs\gd_upload.php on line 59

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'E:\xampp\tmp\php13.tmp' to '/upload/banner.jpg' in E:\xampp\htdocs\gd_upload.php on line 59
Error processing uploaded file banner.jpg

i have created "upload" folder in E:/Xampp/htdocs

i have amended this in that script

$upload_dir = "e:/www/htdocs/upload";

I would venture to say it has something to do with the path you're trying to use. I would think that since you appear to be on a Windows box, the path you'd want to move the file to would need to either be relative (upload/banner.jpg without the leading /) or full including the drive letter before the path.

hi patrick

if i change

move_uploaded_file($_FILES['file']['tmp_name'], "/upload/" . $_FILES['file']['name']);

to

move_uploaded_file($_FILES['file']['tmp_name'], "upload/" . $_FILES['file']['name']);

then i get error

Error processing uploaded file banner.jpg
whether i remove the slash from front or slash from back of "upload" i get the same error.
