iPhoto: Low Quality warning buying a book

[jumbb]

Hi! I'm currently making a book in iPhoto and when i try to buy it this window pops:

Any idea on why this happens or how to fix it?
thanks!

It means the source photos are low resolution and might not print very well at the size chosen.
You can't really "fix" it without using higher resolution photos or using a different book layout that uses smaller pictures

As Phil A. posted, you images are too small,e.g., low resolution to be used in a book without affecting the quality of the final output.

What resolution/quality did you shoot them at? Did you export them from another application and selected a small resolution?

Hi! Thanks for your answers!
I just exported them from iPhoto, all the pictures were taken with my digital camera. I am making another one, with almost the same pictures and it doesn't show the pop-up with that one, so maybe one of the pictures is not good...
