I would give the same advice as GUEST above. Desktop publishing (DTP) allows complete control over what is on your page, whereas word processors think they know better and move things as soon as you add something else.
to use DTP, write your text using a notepad programme, then format it after importing into the DTP. Likewise edit pictures in a specialist editor then use DTP for exact size and cropping.
I have used Scribus which is free and does a good job.
With DTP, you do have to position boxes on a blank page, then fill them with text, colour or image. Once they are in position, you have much finer control. You can move things by fractions of a centimetre but do it by typing a number. You can make a picture smaller by typing a percentage.
Once you start thinking DTP rather than Word processor it becomes simple. The best thing is you have total control over each individual box.
Quack!
