thanks everyone for your responses. i got ahold of someone on the phone at photopass, and he said they don't know why the triangles are showing up, it's just a glitch. he had me on hold for awhile, came back and had it fixed for me. he said he had to delete my pages and put them back exactly how i had them, and that got rid of the triangles. now, another problem - i just spent three hours working on the book, was on a roll, no problems, just wanted to get it finished so i stupidly did not stop to save it every so often, then my whole screen went blank, except for a grey exclamation mark in the middle. so, i guess the last 3 hours were a waste! i am so upset, i'm ready to cry! i think i am not going to do this photobook after any more trips! so many problems, so frustrating! good luck to anyone else attempting one!
