Hello. May I ask: I am using Acrobat 6.0.2, and having trouble formatting a PDF created from multiple (jpeg) files. Each page is formatted to A4 size, portrait. But when I create the PDF, each sheet appears as tiny, in the middle of a huge white page.

Hello.  May I ask:  I am using Acrobat 6.0.2, and having trouble formatting a PDF created from multiple (jpeg) files.  Each page is formatted to A4 size, portrait.  But when I create the PDF, each sheet appears as tiny, in the middle of a huge white page.  I cannot seem to find any controls to adjust this.  Any advice appreciated.
