Bug on GIF files

[truchi]

Hello,

I found a strange behaviour when using GIF files with default media config.
I have:

• Grav@1.1.17
• default media config: GIF's type is 'animated'
• a page (foo.lang.md) with a headers' key containing a GIF filename (bar.gif)
• an alternative for this file (i.e. bar.gif & bar@2x.gif in the page folder) (I guess this is important to reproduce bug)
• a twig template calling page.media to retrieve GIF's URL

I get:

Twig_Error_Runtime
An exception has been thrown during the rendering of a template ("Division by zero").

On the line calling page.media.

The line throwing 'Division by 0' is actually system/src/Grav/Common/Page/Media.php:144
The object used here does not have width and height because MediumFactory gives me a StaticImageMedium (system/src/Grav/Common/Page/Medium/MediumFactory.php:87). Everything is fine with 'image'.

Doc is cool but should dig deeper for this kind of stuff.
Hope this helps!

I'm pretty sure we are relegating all gifs to be animated as we can't tell animated from non animated. And then you are trying to do retina which is not support for animated types. Does it work if you remove the @2x version?

I can confirm it's specifically the @2x and the fact that this image is not actually resizable.
