===What you have to do=== 
 #Go to Wikipedia:Image copyright tags and choose a copyright tag. If you want more informations about the licenses, go to Wikipedia:Copyright FAQ#Licenses. 
 #Go to Image:MySisterAndMe.jpg and add the tag you choosed. For example, for self works released under GFDL, add . 
 After conclusion of this 2 points, the image is accepted on Wikipedia. Plus, if you can write "Dumbass!", as you did, on my talk page, you can also insert a copyright tag. I hope your words for now on will be moderated, otherwise I have to report you to the administrators. We don't want that happen, would you? Have a good work! Regards,
