iphoto to iphone without itunes sync

I know this subject has been raised before and I have read through plenty of different suggestions but none resolve my problem.

My Macbook that I use to sync my iphone to is in the shop for a repair. (Battery not charging).

I have just returned from my holiday and I wanted to put my photos on to my iphone. I borrowed my sisters macbook (os x 10.5.8). I uploaded all my photos then connected my iphone hoping I could simply drag the album on to my phone.

I have an iphone 5 so my sisters macbook is not compatable (requires snow leopard). So trying to sync with her itunes is out of the question.

Is there another way? I have tried a couple of apps but they all require snow leopard. Surely there is an easy way to perform a simple task?

Thanks.
