Be careful for bad characters in filenames. You should probably
preg_replace a few things in the filename first (&*/;). You may also need
to code something warning the user if they are about to overwrite a file
whose name already exists.
I usually just name a file based on the timestamp, i.e.,
$parts = explode(' ',microtime());
$parts[0] = substr($parts[0],2);
$file_name = $parts[1] . $parts[0] . $file_extension;
You should also look at using the GetImageSize function to determine whether
or not the file is really an image.
Good luck.
