I am making a photo book on shutterfly.com but 6 or 7 of my pics come up with the little exclamation point saying that my resolution may be too low. I can't change them because the book is for a certain event and these are the only pics I have. Has anyone ever had the exclamation/triangle warning come up but used those pics anyway and gotten the book back? I need to know if it's going to come out too fuzzy because this is a gift and I want it to look nice. Thanks!!
