Hi Dionneewalshh,
Welcome to the Apple Support Communities!
I understand that you would like to restore your iPhone from a backup to recover pictures, but have thus far been unsuccessful. Without knowing what kind of backup you are attempting to restore from, I would suggest trying to restore from both iTunes and iCloud backups, if you have them available. The attached article will explain how to restore from each.
Back up and restore your iPhone, iPad, or iPod touch using iCloud or iTunes - Apple Support
If you do not have another backup to try and restore from, please let me know what exactly is happening when you restore from the backup you do have. Does the restore from backup not finish or give you an error? Does it complete and just not bring back the pictures you want to recover?
Best regards,
Joe
