If you're not doing any error checking and are expecting a user to upload an image.. it can
pass! Even if it's not an image.
Basic error checking would look like this
<?php
if(!$img_info = getimagesize($some_image))
{
die('You did not upload an image!');
}
?>
However, this will generate a warning, so use of the error supressing operator is advised.
<?php
if(!$img_info = @getimagesize($some_image))
{
die('You did not upload an image!');
}
?>
Seems elementary to some, but I remember this getting me back in the day, when users could upload
straight text files to my database. (i've since learned better security.. heh ;))
Hope that helps a few of the newbies out there. Good luck!
