Getting iTunes sharing error when trying to share iPhoto journals?

I am trying to get information from my iPad onto my macair. I have about 12 iPhoto journals on the iPad I am trying to export to the mac as html files.

I successfully did 3, but now I am getting an iTunes sharing error, it says ''there is not enough space left on this device to share all of the selected items''.

I know the iPad is full and I am trying to move all the files to free up space. My first step was to move the journals then I plan to move all the underlying photos and albums from my recent overseas trip, mostly stored in iPhoto and camera roll.

I have the iPad connected via usb. I would have thought this was a straight data transfer? Or is it using iCloud in some way as I know that is at capacity also.

Any help you can give would be much appreciated.
