iPhoto photo book has vertical lines on some photos
Help! I am just finishing a 100-page photo book containing 450 photos. I am in the final edit and hope to order book today.
Suddenly I have thin vertical lines on left pages which go through all photos. One line on some pages, 2 lines on others spaced a few inches apart, both running vertically. I tried closing iPhoto and re-opening. Vertical lines are now on left side, and were on right before I closed and re-opened. Lines almost appear as if a different photo was on page prior and it never entirely disappeared. It appears line is the same on each page, partially white and partially blue, which seems like a thin slice of the same photo.
the only thing I just did was move about 5 photos from Dropbox onto desktop, then import to iPhoto.
Seems like a glitch. Any suggestions? Thank you.
