Image Utilities

In my school server with my friends we send notes (classwork, homework, etc.)to each other. Compared to a medium like whatsapp it is very tough. It would be amazing if you could implement the following features:-
1)Being able to crop and rotate images while sending them.

2)Being able to collapse images- When we send notes sometimes it goes up to 20 pictures and it clutters up our whole channel.

3)Grouping images - Being able to group images after sending them, like if you were to send 8 pages of english and 10 pages of math together , being able to edit the message and group them so it is easier for the person we are sending them to.

4)When someone sends me notes , especially on the desktop app it opens a tiny image and is very hard to see and the only way to see it is by opening original in the browser, so if we could have an option for the person wanting to see the image to zoom in and rotate incase the sender has not sent them right

5)Being able to scroll through images which are sent together as it is very annoying to exit the image then move to the next one

6)While dragging and dropping multiple images from desktop , to be able to rearrange the order or for it to send in order from the 1st selected one
