Add Gallery Slideshow Option in Briefings

[JamesPoeschel]

I think it would be very handy to have the option to page through multiple pictures in a gallery within a briefings slide, similar to the gallery option in popups. As of now, the images in the gallery get cropped. Attached is an example of a gallery with three images on the right panel. I like the fact that we can zoom into these images while presenting, but at first glance it looks very messy.

@JamesPoeschel -- Thanks for sharing your feedback!

We are evaluating how we could improve the layout algorithm and/or provide more control to improve how things look in some situations for the image gallery in briefings. In general, galleries look better when there are five or more images.

For now, you can adjust whether each image is set to FILL or FIT its container in the individual image options, which may help in some cases.

The Fit option is very nice to have. Thank you!
