I have an app where the user draws to an HTML5 canvas, and then is presented an option to save it to the server. Currently a button that says "Save" is shown, which instructs the server to create a permanent link to the canvas, and then the user is redirected to that permanent link. However, I don't think "Save" conveys exactly what the button will do, and might cause confusion with a "Download" button next to it which allows the user to save the canvas as an image to their computer.
I could call the button "Share", but I'm not sure sharing is exactly what is happening. I've also thought about "Permalink", but I'm not sure users know exactly what that would be. Perhaps "Upload" as opposed to "Download", but I have an option where users can upload an image to the canvas, so that would be confusing as well.
So what should the button say? Or am I overthinking it and is "Save" a perfectly good way to describe what I'm doing?
