I have used an example of upload download file by ;SITEPOINT Build Your Own Database-Driven Website Using PHP & MySQL'. Chapter 11 the complete script for download and upload the file.
I found that my uploaded picture was having problem after I download it to my computer and I cannot view it.
When I try on txt file, I found out that the downloaded txt file is added with html code above my original *.php file(Where the link of download is located). Something like this :
<html>
<head>
<title></title>
</head>
<body background="images/bg.gif" link="black" vlink="black">
<font color="black">
(then the original text is here)
May I know what's the problem?
