I know I'm very annoying asking so many questions xP But.. Just wondering!

The first time I reformat my iPhone, I backed it up when iTunes asked me to, after the reformat, I used the backup, got back all my data INCLUDING the weFit button on my keyboard(Its something like a world..?)
So.. One of the sifus here adviced me not to use the backup, instead sync with your iTunes.
After that I reformat AGAIN, created a new iPhone profile(?) and every single of my data was back EXCEPT for my pictures.
Does anyone have any idea how to retrieve the pictures?
