Photos from Dropbox -> Camera Roll? (lost photos after 5.1.1 update)

Hi all,

I've just updated my phone to 5.1.1 and unfortunately had to do a restore (stupid iTunes for Windows...) all of my app data was recovered without a problem (that I can tell) but unfortunately my camera roll is absolutely blank, save for the one screenshot I accidentally just took whilst trying to hard reset my phone!

Luckily the Dropbox app has meant I haven't lost everything (thank god!) but I'm wondering how I can get those photos back into the camera roll?

Many thanks

Thanks, that was tempting but I only had maybe 300 or so photos in my camera roll, as opposed to the 3,000 or so saved in Dropbox - ideally I only want to restore the 300 or so I had in my camera roll (they're my favourite shots dating back from ages ago, also some useful ones I often refer to, I could go through Dropbox and sort through them, but it'd probably take me a good couple of days of sorting)

the update was constantly failing, so I had to do a restore, but in turn meant I lost all of my photos!
