How to mettre en ligne 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. toi just need to check the size of the image. Here's some ex:
images 250px par 250px ou smaller will go to icons.
Images: 1000px par 1000px ou larger will go to wallpaper. images 400px par 400px ou larger go to photos ou fanart (but that's par choice)

Hope that helps :)
