getimagesize

[Laszl0w]

if(isset($_POST["submit"]))
    {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "Ez a fájl egy kép - " . $check["mime"] . ".<br>";//this is a picture
        $uploadOk = 1;
    } 
    else
    {
        echo "Ez a fájl nem kép.<br>";//This is not a picture
        $uploadOk = 0;
    }
}

It allows:
jpg,jpeg,gif,png and some bmps
but it doesnt allow some bmp files. why?

This can be caused beacuse of some PHP memory limitations. BMP is a pretty raw format. Change this in the php.ini

php_value upload_max_filesize 5M
php_value post_max_size 8M
php_value max_input_time 1800
LimitRequestBody 0
