How do I add a screenshot I already have?

You don't have to capture in-app. Any image you already have works, and these paths don't need screen capture, so they work in Firefox, Safari, and on touch devices too.

• Paste: copy an image (for example a Mac screenshot) and press Cmd+V / Ctrl+V anywhere in the editor.
• Drag and drop: drag the image file onto the editor.
• Add image: click the Add image button and pick a file.

However it gets in, it becomes a normal screenshot item, so you can crop it and drop pins on it the same way.
