Restore my backup iphone without losing the photos I have on my phone now?

I have had an iphone for about 3 years so I have a backup saved with a lot of information, contacts, apps, pics, etc. that I REALLY want back on my phone. However, my iphone broke while on vacation. I had to stop at an apple store and get a new one. I didn't have my Mac with me on this vacation so I just planned on restoring when I returned home. However, on the trip, I got engaged so I took a lot of pictures on my new phone that I don't want to lose. Is there anyway to save those new pictures AND restore my backup??? PLEASE help!
