Photo Book Help - low resolution?

[jacksmomtobe]

I'm trying to create a photo book on Shutterfly for DH's b-day and on one of the photos I'm getting a low resolution message. I read their blurb on it but it really doesn't tell me either what I should do to try to fix it. I've made that photo the smallest size out of the options and that helped with another photo but not this one. My question is is there a way to fix it? And if I can't will it come out terrible in the photo book or is there a chance it will be ok? This is my first time creating a photo book.
Thanks!

usually one of those low-res warnings means that the resolution of the image u are uploading is so low that it likely won't look very good when printed (will look grainy, etc). happens a lot if the image was something you got in an email or something (image was reduced/compressed for size). ithe only thing u can do to fix it is to find the original size version of the image (or a larger version of it, that isn't as compressed).
