Image swipe feature on Zulip mobile

[CuriousMonkey7]

On Zulip web and desktop, when we click on the image, it opens in the image preview, and in the image preview, we can see other images(refer below screenshot) using arrow keys or by clicking on the image present in the list, but in mobile, there is no option for image swipe. If we want to see another image, we have to go back and select that image. And I think it's not a very good experience. We should have a similar image swipe feature on Zulip mobile. While discussing on Zulip organization chat, we agreed to have this feature in mobile. Some suggestion from the discussion:

• We don't want the image list to appear(unlike Zulip desktop) on mobile. On mobile, it'll be intuitive to swipe.
• And if we are displaying the image list, there must be an easy way to appear/disappear list so that while viewing a particular image, you can focus on the image.
