Currently, we need to save pictures and then upload them in this editor, it would be nice to be able to copy and paste images directly to the editor. Technically it is possible, for example take a look at this scenario:
1) Visit any website using the latest version of Microsoft Edge
2) Right click on a page and click on Web capture and select an area and take snapshot and copy it.
3) Then visit https://www.bing.com/visualsearch
4) Right click on Paste image or URL and paste the image from clipboard
5) You will notice image from clipboard has been paste and will be search in Bing
Therefore, with current web standard it is possible to directly paste image from clipboard and there is a need to implement a function to save it and associated with our editor. I recommend to implement this feature for editor of this website and it will improve the user experience greatly.
