Features request: filetype filtering, new layout about gallery-card

[TarheelGrad1998]

Are you using the files component? If so you can limit to just images from there, using this parameter:
filter: '**/*.jpg'
However there is currently no filtering when using the Media Source. That would have to be an addition.

You can do horizontal thumbnails but, as is, you can't hide the main picture. I haven't tried this, but in theory you should be able to do that as well as change the height using something like card_mod:

Filtering for images only can be achieved in v3.4 using the following parameter:
include_video: false
