Use snipping tool to take a picture of the image. If you need to hover the image first you can set a timer using the clock icon on snipping tool.
Control S to save it.
Imgur.com. Upload the picture. Right click on the image when it loads and open in new tab. Close the tab that just opened and right click open in new tab again(for some reason if you do it too fast the url starts with “blob” and it doesn’t work)
Copy that page’s url.
Click the 6th image from the left on the toolbar at the top when making a post on jsp(the photo image). The moment you click on the image picture hit control v
