Drag and Drop pictures from browser

I often browse reddit on my pc and I like to share pictures and stuff with friends on discord. I always have to rightclick the image and then click copy, then go over to discord and press ctrl+c to post it. It would be nice to be able to just press and hold the left mousebutton on the image, then just drag it over to the discord tab and drop it on the textbar to post it on a server or DMs.
