Calendar Photos - The Yellow Alert Icon and Cropping

Question

This also happens in iPhoto 5/6 when creating a book.
When placing the photo in the calendar many times I get a Yellow "Alert" icon that shows that the photo does not fit into the window/box I placed it into!!!
1. How do I get rid of the Yellow Alert Icon, or how do I make the photo place properly.
2. Why is there NOTHING in Help about the Yellow Alert Icon and how to get rid of it???
Thx Much to anyone who can help.

Answer 1

I found this by entering "yellow" in the "Help" screen search box. The topic includes samples that illustrate the yellow icon (which, unfortuately, did not reproduce in the post):
What to do about a low-resolution warning
A digital photo is made up of millions of individual dots of color, called pixels. A photo's "resolution" is the number of dots per inch (dpi) that it contains. The higher the resolution, the more dots per inch. Some photos may look jagged or blurry when printed if their resolution is too low.
When you design a book, calendar, or card, or order prints, a warning symbol indicates any low-resolution photos:
To improve a photo's print quality:
Choose a smaller print size. In a book or calendar layout, you can do this by increasing the number of photos per page.
If you previously cropped the photo, revert to its original version and crop off a smaller portion, or leave it uncropped.
If you positioned a photo within its frame by zooming in on it, zoom out of the photo.
If you get a low-resolution warning after trying these methods, you can still order prints of the image or include it in your book, calendar, or card, but it may not print as clearly as your other photos.
