Using images for photobooks

[Miss Frizzle]

When you make a photobook on blurb.com, or any other photobook source, do you do anything special to your pictures in photoshop before you upload them? I am wondering if I should resize each photo, adjust the resolution, etc. Or if I should just upload them as they are. What do you think?

As far as Blurb is concerned, they have several "suggestions" on their site as to what image requirements work best. Just look through their Help section,,,,
