Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
IDK, keep trying different things to see what works for you bro. that's what worked for me. Did you right click the image and then "Copy Image Location"?
I'm interested in your Deino. Is it Male or Female?
You can add the picture of the Pokemon by click on the Clip Art button, then it just asks for the URL of the image. You can get them here:http://floatzel.net/pokemon/black-white/sprites/
Then just right click on the Pokemon you want and select Copy Image Location. Then erase the http://, and paste the URL and you got the sprite. Hope that helped.
