Alright, so while in-game press the F2 button to take a screenshot. Then come on the forums and make a new topic or reply or whatever and click on the "Host an image" button, and make sure the "file" tab is selected and go to choose file. Then, on the search bar of the pop-up menu type in %appdata% and you may have to click on roaming, and then click on the file named .minecraft, go to screenshot file and double-click on one of the screenshot. Then press the host button and copy the "image" formula and paste it into the topic or whatever you are doing. Hope this helped!
