if( !valid_src_mime_type( $mime_type ) && !(preg_match('@windows@', php_uname()))) {olarak deneyin.
Teşekkürler denedim. Şu an sanırım sadece şu hatayı verecek. Resmin yoluna baktığımda şu hatayı alıyorum.
Invalid src mime type:
Hemen altta internetten bulup değiştirdiğim kısımlar bulunmakta. Kontrol ederseniz ve nerede hata yaptığımı söylerseniz çok sevinirim. Teşekkürler
