Gallery on a local hosted intranet site displays in every browser, including MS Edge, but not IE (version 11 is what our base install uses). 
I am NOT a web designer/developer/html coder by any stretch so I saw the iFrame option and the Atahualpa option, but first have no idea how to incorporate them (it seems the Atahualpa is related to Wordpress site which I am not using) and maybe I just don't know where to insert the
"<iframe src="http://www.example.com/gallery_folder/index.html" width="800" height="600" frameborder="0" scrolling="no"></iframe>" into my code.

Regardless it still isn't working for IE, which is unfortunately the default browser for most of my users, so when I send the link they see no pic.

Thanks
