File upload problem using apache

[lanza]

Hi!
Im running apache on windows XP proffessional and i wanted to make a simple file upload script to my computer. The problem is that when i upload from my computer to my computer the file gets uploaded but when somebody else tries to upload it remotely, nothing happens - no error messages - it just wont upload. Is there a problem with my apache configuring skills or something else. The file to be uploaded is JPEG so different formats shouldnt be the case. I have added the code below:

<?php 
    if(($_FILES['file']['type']=='image/jpeg')&&($_FILES['file']['size']<1000000)){ 
        $pic='/web/Pic/Pictures/'.$_POST['name'].'.jpeg'; 
        move_uploaded_file($_FILES['file']['tmp_name'], $pic); 
    } 
?> 

<form action='upload.php' method='POST' ENCTYPE='multipart/form-data'> 
    <input type='file' name='file' size='5'><br /> 
    <input type='text' name='name' /> 
    <input type='submit' name='submit' value='LISA PILT' /> 
</form>

Thanks in advance.
