Wondering if anyone can help me?

I've created a newsletter in Indesign and have placed images and coloured boxes to the edges of some of my pages. But when I export the newsletter to PDF the image edges are showing up on the adjacent page (even though they are only on one page in Indesign). How can I stop this?

Some more info about your export settings please ... have you got trims and bleeds turned on? Is your paper custom so that all marks and bleeds will show (otherwise images could go onto other pages).
Are you printing this to a desktop printer or a commercial printer?

And the version of ID. There was a bug in, I think CS, that could cause items touching the spine to appear on the other half of a spread, as well. The solution for that was to move them into the page 1 pt.
