Yes, you girlfriend could have male friend. The question are, do the picture upload in public/social media or privately send to her by some boys. If it in public I think it alright. But if it privately send to her, maybe you need to talk with her heart to heart. Don't mad at her especially she don't send any picture. It can be helped when other boys want to hit on her, but you need to prepare by preventing the third parties.
