He's a function to find whether a file is an image:
function is_image($file){
$fp = fopen($file, "r");
$fcont = fread($fp, 15);
fclose($fp);
if(strstr($fcont,"PNG")){
$imagetype = "image/png";
}elseif(strstr($fcont,"GIF")){
$imagetype = "image/gif";
}elseif(strstr($fcont,"JFIF")){
$imagetype = "image/pjpeg";
}elseif(strstr($fcont,"BM")){
$imagetype = "image/bmp";
}
if(isset($imagetype)){
return $true;
}else{
return $false;
}
}
Enjoy! :)
