What is that yellow triangle that appears over my photo?

If you're seeing a yellow triangle with an exclamation point in the middle of a picture, this means your file size is too small for that photo location. This icon is only a warning and won't appear when printed.

While you may still use your photo in this spot, it may appear pixelated when printed.

If the photo looks fine in the Adobe Acrobat preview when zoomed in at 100%, it should be fine when printed.
