It's a very simple website. I say this because its functions are super simple. As the saying goes: survival is the way. But let's not digress, let's talk about it. First, no registration required: this provides convenience for netizens, and perhaps this is one of the reasons many netizens choose it. Second, uploading in three steps. First, write a title for the photo you upload, then upload from your local device, and the next step is optional - describe your image. Finally, click submit and wait for two minutes, and a URL like this will be generated: http://www.picupine.com/9c2788dx. Send this URL to your friends, and they can view the photos inside through this link. That's all.
