It's very simple, just click the pieces you want to add to the chessboard to select them, then click the square on the chessboard you want to add them to. There are buttons to quickly get the start position, empty the board, flip the board and paste in a FEN position that you want to see displayed. To highlight a move you can put it in the little textbox, just put in something like "d2d4" to highlight a move from d2 to d4. If the move is a straight or diagonal line the whole line will be highlighted, otherwise only the two squares will be.
Every change you will make updates the url in the address bar, so you can always just copy that to get a link to this page showing that exact position. If you only want the url to the image you can press the "Copy Image Url" button to copy the url to the clipboard, or press "Download Image" to download the image locally. It is allowed to hotlink images straight from our site, but we make no guarantees about uptime etc (although it's heavily cached on a CDN so it should be fine).
The format we use for the urls is inspired by FEN, in fact you can take a normal FEN, like rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2 and just put it directly after https://chessboardimage.com/ and you have a valid url, you don't even have to go to our site to make it. Try clicking on: https://chessboardimage.com/rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2, it works out of the box, we just discard the part of the FEN we don't use. Want just the url to the image? Do the same thing but add .png to the end. Try this link to see: https://chessboardimage.com/rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2.png. So, hopefully this makes it extremely easy to quickly use this site to generate the images you need.
