How resize pictures in table on PAGES 5.2?

Question

The new version 5.2 was be optmized for import image in table, but how resize these pictures in table?

Answer 1

DO NOT use Pages 5.2.    Use Keynote or Numbers.  The latest versions of these apps are stable.  Pages 5.2 nothing but trouble.
Here is what I do with my art, which must be perfect for commercial printing and other purposes.
Export the page with your table and art out as a PDF.  Then bring the PDF into Adobe Illustator and make any changes you need to get the art looing exactly like what you want.  Save the art from AI ouit to PDF.  AI creates bullet proof PDF files.  Then drag the clean PDF back into Pages.
One reason AI is the preferred route is that Adobe comlpliant PDF files  are the standard in the commercial printing industry.  These days, all files going to commercial printers must be in clean PDF format.  As you would expect, there are some excellent apps for pre-flighint PDF files.
The final reason for using PDF for art is that your illustrations will move cleanly into iBook Author for iBooks and apps for creating international standard ePubs and Amazon MOBI files.
