My phone has gone into recovery mode, but I want to save my pictures before I restore it. What do I do?

So yesterday I tried to reboot my phone but then it never finished rebooting as the Apple logo is stuck on my phone. I brought to the store for help but they say you have to only restore. Now my phone is in recovery mode and I can't exit it. I forgot to back up/ import my photos so I really really don't want to lose them so I don't want to restore. I know it's my fault not backing up but is there any way I can access to my phone again or exit the recovery mode. I tried updating but it doesn't work as there would error (4). Please can someone suggest what I should do. I know a lot of you guys had this problem and if you were able to fix it can you please tell me how you've done it? Please I'm so desperate
