Have you ever set up icloud? It should have a back up of all your data. Make sure you do before restoring. That is probably your only option.
Itunes backs up your phone to your
computer or icloud.
go to itunes>preferences> and click on devices and you should see your backups
IF you just took those photos and it did not back up since then, you likely could lose them after doing a restore. Restoring with no backup will lose everything. You have been warned
Also login to another
computer or account and see if that makes a difference.
