How to đăng tải a picture to this club as a regular size photo?

It just depends on the size of the image. Whatever the size of the image that's where it's going to go. bạn just need to check the size of the image. Here's some ex:
hình ảnh 250px bởi 250px hoặc smaller will go to icons.
Images: 1000px bởi 1000px hoặc larger will go to wallpaper. hình ảnh 400px bởi 400px hoặc larger go to các bức ảnh hoặc fanart (but that's bởi choice)

Hope that helps :)
