Support pasting images from clipboard as file attachement
Windows 10 has a fancy screenshot tool: When pressing Win+Shift+S, one can select a rectangle on the screen and it is immidiatly copied into the clipboard as image. In chat programs like WhatsApp Desktop, it is possible to paste this image and it is send to the other person. This way one can simply share screenshots without having to store the screenshot as file (which means selecting a directory and file), then selecting this directory and file again to send it to somebody, and having to delete the file afterwards.
Description of the new feature
What I actually want is quite simple, though I can't say how hard it is to implement: When there is a image in the clipboard and the user selects Paste
or presses Ctrl+V in the chat window, store the image in the temporary folder, send it to the recipient and delete it afterwards. This would be a huge improvement of my current workflow.
