More print output questions

I am generating a print output from RoboHelp 10. I have some questions:

1. Is there a way in RoboHelp or in Word to scale the size of all images in the document to a constant width?

2. Is there a way to output a word document in 2 columns?

3. How do we create hyperlinks to the keywords in index? When I output Word output with index, I see only page numbers and no links to the document topics.

Best regards,

Vinay
