iphoto low quality pictures

How high is up?

It means that it may print at a lower quality - it may be a little pixelated or a lot pixelated

How much totally depends on the pixel size of the photo and the physical size of the print

the basic rule is that photo smust be 150 DPI or more for good prints - so you divide the pixels in each dimension by the inches being printed in that difection - if the answer is 149 then things should be fine - it is is 25 then things will be very bad

What are the pixel dimensions of the pictures giving that warning and what size frame are they in? According to iPhoto's preference file the warning occurs in iPhoto 7 (08) if the resulting dpi falls below 180 (BookWarningImageDPI).

You can determine what size image will be at the cutoff by dividing the pixel dimensions of the image by 140.

So if you had a 1600 x 1200 image the size would be around 8.8" x 6.6".

You can create a PDF of the book according to this Apple Document and check it to see if the image will meed your expectations: iPhoto, Aperture: Previewing an order in iPhoto or Aperture

Not actually a good test as a 72 DPI image looks perfect on a display screen but prints terrible - best to go by actual printed DPI rather than screen display since a screen is a totally different anminal and both colors and resolution work completely differently for screens

Apple's suggested minimum pixel dimensions for disserent size prints are in the link I provided

doing the calulation I recommended is the best idea

If you view the PDF at Acutal Size you cab get an idea of what the pixelation/blurriness will be.
