I have an image of an A4 brochure I want to turn it into a PDF file so as I
can place link to it from on a web page
I have adobe acrobat professional 7. I convert the image to a pdf ok but
two things happen.

1. The pdf converted image appears as a thumbnail in adobe acrobat , It can
be enlarged by using the zoom tool. I then give it a name and save it when
I upload the page and then click on the text link to print the Brochure (pdf
file)
Adobe Acrbat opens not Adobe reader and the brochure appears as a thumb nail, again
it can be enlarged with the zoom.

When I go to print it from adobe, it only fills two thirds of the A4 page am unable
to get it to print to a full A4.

1. when I create the pdf how can I get it to sho in full A4 size.
2. Why does Acrobat keep opening and not Adobe Reader when the web page link is clicked.
3. Why wont it print to a full page.

TIA
