Facebook Image URL is invalid (Graph API)

Question

I am developing a Facebook game. In that the 10 opponent picture is displayed. I had saved these profile images in the database once the user had registered.

I am using PHP to echo the image, but the problem is some pictures are being displayed and others are giving me a '404' / '400' or 'Invalid URL ' not found error. Example: ( These images earlier used to be displayed but not anymore)

https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-snc6/199347_134645999940053_5814468_q.jpg.

1. How can I fix this problem? Or find some alternative so that the broken link of these images is not displayed.

2. I am having the user ID of these users, Can I somehow generate new picture if these picture links

   are detected as broken?

3. Is it advisable to hotlink the Picture URLs ? I don't want this problem to occur again?

I would appreciate if some one could help me.
