I use Google Drive to store images for DL. Dropbox had an easier way of sharing but now Google is.
I use AutoHotkey to take a view URL and automatically, on paste, convert it into an embed link. Most of the stuff I use in DL are screenshots and similar “how to” images. I just plop them in a specific folder which is set to shared; this way I don’t need to set sharing permissions on a per file basis.
