Hi Neil, In regards to the large size of the modified PDF file here is something you can try. The procedure is different depending on whether you are running OS X 10.7 Lion or an earlier version of the OS.
In Lion: 1) Display the PDF in Preview 2) At the top of the window, just to the right of the document title there is a drop down menu that may display to the word "Locked" or it may be blank. In either case hover the cursor over this area and a down arrow will appear . Click and select "Duplicate" from this drop down menu. 3) For the new window that is created with an animation, select from the main system menu File > Save... 4) Here's the crucial step -- in the drop down dialog used to save the file, set the Quartz Filter to Reduce File Size. The pre-Lion process is a bit easier: 1) Display the PDF in Preview 2) From the main system menu select File > Save As... 3) In the drop down dialog used to save the file, set the Quartz Filter to Reduce File Size. A quick note, I did not try this on a pre-Lion version of the OS so I am half guessing, and half filling in blanks from memory for that section. Let me know if it works.
