In most cases, BAM! relies on your browser's native image handling to display images.  As an example, TIFF images are not commonly supported among the major browsers outside of IE and Edge.  You can check browser support for image types here: https://en.wikipedia.org/wiki/Comparison_of_web_browsers#Image_format_support.  


If you have a valid image that is not being displayed, please contact BAM! support to review your case.
