Adjusting:
You adjust the image with the Property Inspector.
Window/Properties or Modify/Select Properties.
You can scale it with
the width (W) and Height (H) boxes or stretch the image with the handles around
the image.
You can set it back
to the original size with the "Reset Size" button.
if you don't see all the options, use the expander button on the bottom
right of the panel.
*note: changing the image
size does not reduce the file size of the image, so if you find yourself scaling
down a lot use images closer to the size that you will want them to be.
