![if you just want to input a part of your image, then crop the image by moving and sizing the black frame. only the part within the black frame will be inputed. if your image has already the proper size, then you don′t need to crop it, in this case you can click on the “disable crop” button, then the whole image will be inputed. certainly you can also rotate your image in case of need. finally click on the button “add as comment” or “add as answer”. that′s all.](https://www.tinkutara.com/question/Q95274.png)
