[FR] Photo gallery improvements

### Description

- [ ] You can move the image out of the view while panning.
- [ ] You never see the end when displaying an album as a grid with many images. There should be a fixed number of shown images (like 20-30) and a button to show/hide the rest.
- [ ] When you select many images from an image block, there should be a way to convert it into a gallery.
- [ ] Clicking outside of an image should exit out of the image viewer.
