Hello there, you can take a screenshot of your ninjas by pressing the "PrtSc" or "PrntScrn" on the top right part of your keyboard. By posting a screenshot, players can help you much easier. Or you can try using our search bar for different strategies and build ^^

You can't put the URL from your PC to upload. You click the "Image" then browse and select the file when you are replying, you can see that on the top left of the text box.
