How to not set iphone 5 as new iphone or restore from backup?

I got an iphone during a trip overseas and i have been taking pictures with. I didn't connect my iphone to itunes as soon as i bought it because i didn't bring my laptop. Now i want to sync my iphone to itunes but in order to do so i have to backup from my previous iphone's files or set up as new iphone. The problem is i don't want to lose all the pictures i took.

Well transfer the pics. Plug into computer & on Windows go to My Computer & you'd see the iPhone there to open & take the pics from & on a Mac use Image Capture.
