How to carica 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. te just need to check the size of the image. Here's some ex:
immagini 250px da 250px o smaller will go to icons.
Images: 1000px da 1000px o larger will go to wallpaper. immagini 400px da 400px o larger go to foto o fanart (but that's da choice)

Hope that helps :)
