@manuela: dropzonejs.com gives a 404
404?? - not for me, it works without problems in multiple test's on different day's
my personal opinion- two different places - 1. media administration - 2. section editing in wysiwyg editor
to #1 - media administration
a solution via dropzone, pluploader (like OFA), fineuploader (like Foldergallery) etc looks (for me) very simple. Big Problem here: what kind of uploader is the best (for every solution/uploader you found also negative posts in the web) and does it work for every user in every browser?? Can i use this third-party-addon also in 2020 (for free/open source), the EOL for WB 2.10.x or is it needed, to upgrade this every mounths? from my point, best solution for me is dropzone, very small, very simple to integrate it into the backend theme, but... we work only with the DefaultTheme (ACP-Theme), whats happend with the other themes like the example from crnogorac081? its of course possible, to write a tutorial for that or to give help in the integration, if somebody make the service for this theme.
at this point, this day, i'm not sure, what happend in the media administration in the next wb-version > WB 2.11, we talk a lot about the construct, the basics, but not in details. But if we add a solution now, in the next coming WB 2.10.1, we can use it for the next four years in WB 2.10.x and WB 2.11.x at minimum
to #2 - section editing in wysiwyg editor
the wysiwyg editor like our prefered ckeditor has a own image handling, working with a plugin. this ckeditor has also a integrated file browser, but disabled at the moment, because, it works unsafe
in the case of user group permissions . that means, in special cases, specially on pages with different admin groups, its possible, that a user get the permission to upload/delete pictures in a group with no permissions for that, if there is also another group as page admin with permissions for that.
the file browser works without problems (or no reported problems

), if you're a single admin on this page.
the file browser is a globale element in the ckeditor and use only some predefined paths and some special defined functions to get the permissions.
From my point and without test's, its also possible to add here a uploader-addon like dropzone etc, but you need then a wb-own plugin or wb-own filebrowser, that disabled the original, only possible to upgrade via module-upgrade (at the moment, its possible, to upgrade the ckeditor on a private way via upload from the build-config.js)
also from my point and without test's: no chance to add a dropzone inside of the wysiwyg-form and maybe moving the dropped picture via drag&drop to the wished position (i remember that I had seen such a solution before in a different system)
I don't see anyone implying the Dev-Team is being lazy, or even that they should look into this.
stay cool

it was only a additional information, because, it looks maybe quite to the outside, but there are a lot of things to do in the background (change all projects to https, upgrade the forum, re-order the whole permissions there, working on the tickets, prepared the WB 2.10.1-Test etc, etc,
read the words as: we stay here and we read also everything
