Suggest adding a toggle button

[leelax22]

I am using the plugin very well. I'm posting this because there's a feature I think it would be good to add.

I use data that is not important enough to be stored locally or that needs to be uploaded to a blog by uploading it to imgur. (In the case of github pages, there is a 1GB limit.) Even when uploaded to imgur, the file is preserved for a long time. It seems like it can be done, but there doesn't seem to be any evidence for how much it will be preserved, and it feels more unsafe than being stored locally.

So, I think it would be convenient to have a toggle key for whether or not to use imgur with the ribbon. Now I have to confirm every time.

Even if no features are added, it works well as is. Thank you for creating a great plugin. I'm using it well.
