iPad app to convert multiple photos to a single pdf Does anyone know an app to convert multiple photos from the iPad Camera Roll into a single PDF?

Alternatively, an app that lets you take photos with the iPad camera and saves them into a single PDF would be good - ability to rotate photos is important as this is mostly for 'scanning' document pages using the iPad.
Even simpler than Pages, you can use iBooks


Step 1: Select all photos you want to combine into one pdf within
your Camera Roll, they should be in the order you want them combined
in 
Step 2: Press the share button (the up arrow in the box at the
top left hand corner of the screen) 
Step 3: Tap iBooks icon prompting to "Save the PDF file in iBooks"


That's it!
