Description
Hi Knightlab,
Here's a bug for published Storymaps when viewed in Firefox 50.0 on Windows 10.
Storymap distorts slide images when published, here's a link to a published example. When I change the dimensions of the browser window, the slide image distorts accordingly.
I need the slide images, engravings, at the correct dimensions, or I can't use Storymap JS for my project.
Since it works in Chrome I'll do it anyway, but it's frustrating. I understand keeping up with browser tweeks is difficult.
Below is a screenshot showing the distorted image in Firefox (on Windows) alongside the original image in Photoshop.
Thanks, Andrew Taylor
