Over the past 6 months I've accumulated lots of various pictures on my iPad. Some were copied over from my iPhone, some saved from emails & some synced via iTunes (from a dedicated folder on my Win 7 laptop).

I have just decided to clear a lot out & delete them, but seem to be having problems actually removing them. I have tried to select & delete them from the iPad itself, but it doesn't give me an active delete button..... & I have tried arranging the folder it syncs with on my laptop to only have the pics I want in it - this just resulted in all of the original pics in there & then duplicates of the synced ones.

It's probably something very simple that I'm missing, but can anyone offer any advice?

Many thanks!
