Symptoms

Warning Next To Pictures
The pictures that appear with a warning may look jagged or blurry when printed (Figures 1 through 3 below). Choose a smaller size print for better quality when ordering prints. When laying out a book, increasing the number of photos on a page will reduce picture size and may eliminate the warning. For better quality, all images should have a minimum of 3.1 megapixels. This generally results in higher-quality images.
If a photo has been cropped, reverting to the original version will increase the picture size and may eliminate the warning.
For quality prints, Kodak recommends these minimum resolutions for the following print sizes:
| Print size | Bitmap resolution size |
| wallet | 640 by 480 pixels |
| 4 by 5 inches | 768 by 512 pixels |
| 5 by 7 inches | 1152 by 768 pixels |
| 8 by 10 inches | 1536 by 1024 pixels |
Higher resolutions than these will generally result in higher quality prints at a given size. Additional information from Kodak on digital imaging can be found in the Kodak Digital Learning Center.

Warning Next to Text Caption
If a warning icon appears next to a text caption it indicates some of the text goes past the given border for a caption. A warning will also appear when ordering the book (See Figure 4). Since the point size of a caption is set by iPhoto (based on the layout chosen), there are two options to make the text fit.
One option is to reduce the amount of text in the caption. Because the dimensions of the caption are predefined, there are no scroll bars so the extra text may not be immediately visible. When visible text is removed, the additional text will appear.
A second option may be to change the font used in the caption. Many fonts have different line and character spacing specifications. So the Chicago font at 11.8 pt will take more space than the Helvetica font at 11.8 pt. Before deleting text, try different fonts to see if any work better. Note that changing the text for one caption affects all other captions of the same type (caption, title, subtitle).
