You see, OperaGX have this feature that let you like, upload images from the clipboard. When you want to upload a image to a website, you need to download the image and then upload it. But with this feature you can just “copy image” and then when you try to upload the image you can select the image from the clipboard without having to download images all day, this can be shown like a little menu where you decide to select something in the clipboard or your PC.
