The simple copy and paste sometimes doesn't work when reading or editing the Jira ticket or story. It doesn't work when using the shortcuts Ctrl+C and Ctrl+V or using the menu displayed by clicking on right mouse button.
This method works for me:
- You have to first click on the image, to display it in a preview mode.
- Then click on it with the right mouse button and choose Copy.
- You should be able to paste it into other Jira story, Paint, Word or Excel.
