I'm nearing the end of the creation of a 100+ page booklet (using Word 2007). The booklet contains advertisements that involve the use of some graphics (primarily JPG format). For ease of placement I've created the ads in individual tables. My problem is that many of the graphics are displaying with top & left gray boundary box lines that are unwanted. When saving in PDF format these lines continue to appear. How do I get rid of these lines around my graphics?
