I need a full page bleed for an image!

Question

I've tried just about everything to figure this one out, but I'm starting to suspect the feature is just not available. I'm working on a book and will self publish it, so I need to put the illustrations into the body of the work. Which isn't hard to do, but I need the image to bleed into the margins, basically span the entire page. The only way I can seem to do this is to eliminate the margins entirely, but of course I need the margins for the text. So, is there a way to eliminate the margins just for the image?
While I'm here I might as well address the other issue I'm having: I need to save an image at 300 DPI but I constantly have problems getting the size right if I do so. I know the max pixels is 2000, but for printing specs I need the cover image for the book to be 6.25x9.25, which comes out to 1875 x 2775 pixels at 300 DPI. Perhaps Appleworks is not the program to do this in, but unfortunately my old iMac has no room for larger programs. Hmm.....Any suggestions?
Thanks!

Hi Paul,
On a typewriter, you'd call then the Margin stops.
If you want to eliminate the headers on pages with pictures, try this addition to Yvan's suggestions:
For the first page where you want a picture, put a section break at the end of the previous page, then go Format > Section...
Set the section to begin on a New Page, and Click the checkbox for Title Page. Click OK.
After inserting the picture, don't use a Section break to move to the next page. Press enter to insert a Column break or shift-enter to insert a Page break (both have the same effect in a single column document).
For each new picture, insert a section break at the end of the page before. The new section will start on a new page, and the headers and footers will be suppressed on this 'Title' page.
