I just tried upload images with questions that I wanted to ask.
But when I tried to upload images, it won't no matter what.
Is there something wrong with it?

Nevermind.
It seems it worked.

Uploading images to this site is, I'm afraid, against the rules due to limited capacity and I'm not sure you really meant to upload 8 image files. The upload function is meant for script logs and things of that nature that don't take up any appreciable web server space. We'll let your thread with the uploads stand for the moment, but what we are meant to do is upload these things to a third party file host and then embed the images by way of linking them in the forum board text editor -- or use the "img" tag to include them, which amounts to the same thing.
