Add a decent photowebpart
Add a photowebpart that shows the content of a picture library in thumbnails. when you click a thumbnail, a popup will appear with the photo in a "normal size" (as available in _w hidden folder) and than you can browse the photos with next/previous buttons, with an option To show the picture in original size.
We’ll be updating the Image gallery web part on modern pages shortly to display images dynamically from a document library, if you have that library backed by a CDN.
Make sure that it supports .SVG files as well, not only the usual suspects - raster ones.
.SVG is officially supported inside MS documents, so it makes sense to make it easier to preview them.

Also, add the ability to show images from a selected view of a library. This would allow metadata filtering to be set on the view, making it easier to use the same library for all images. This would be similar to the Picture Library Slideshow web part available on Classic site pages.

Ability to rotate photo too, as EXIF data is usually ignored on upload in SPO.

And allow us to browse (not just type) not only Image Library as a source but also Document library and just from the root of it but allow us to pick any folder in them. I worked with this lately and it's such a pain in SP 2013.

And also an associated web part for carousel or other styles would be great.
