Since some of you are having a hard time puting picture I did a little tutorial
ok first you got to have an image
then you go to your message and use the host image icon click on parcourir(it will probably not have the same name because my computer is in french)
choose your image and double-click on it or click on it and use open icon
Click on send and wait a bit it take some time to host it
copy the last link
past in the Image icon
There it is enjoy your pic!
