Q: I have gone into itunes, advanced>turn on home sharing- put in apple password and to enable home sharing however took picture and nothing was pushed to my device- can anyone tell me what else I have to do.  Device is not Apple but Genuis told me ok

I have iphone 4s- my laptop is not Apple.  The apple Genius told me I could download app so that pictures would be pushed to my device.  Can't see anything obvious for this.  Was then told to go to itunes, advanced and turn on home sharing - I have done this but picures not being pushed.  Any suggestions?
