A caution regarding image sizes

Each section with the option to upload an image (a "Browse" button) is designed so that images must meet a minimum image size to display correctly (or at all, in many cases). 

If you click "Browse" and upload an image from your computer, you will see the minimum size displayed below the upload button. If you choose an image that doesn't meet the minimum, you will receive an error message.

If you navigate to the media library to browse for an existing image instead of uploading a new one, it is possible to choose one that does not meet the minimum size and you will not get the error message. If an image that does not meet the size requirement is selected in this way, it will appear on the back end (in editing view) but will not display on the front end (what site visitors see).
