Can I add an image to the file database, and/or add an image to a post I plan to make in Discussion? The sandbox doesn't explain how to do it, although I did manage to add (well, preview) an already-existing image called Example.jpg.
If you click on the insert/edit image button you get a window with image options. Within that window, to the right of the "Image URL" textbox, there is a button with mouseover text "Browse." Clicking that will open up a new window that lets you upload files (Choose File) and use files you've already uploaded.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
