I am unable to use a custom image option for a point symbol in an ArcGIS Online web map. I have tried using an image hosted on both Dropbox and Flikr; I continue to receive an error that says "Unable to Load Image" (see attached screenshot). Any suggestions. This feature worked prior to the most recent update to ArcGIS Online.

Update: This feature works with an image hosted on ArcGIS Online but not elsewhere.
