Anyone can create a page. It's not actually that difficult once you get used to it. I've provided a handy tool on the front page in the section "Contributing", where you can simply enter the name of the card into one of the boxes, press create, and all the parameter fields will come up for you to fill in. Just make sure you enter the name in the correct box (the buttons tell you which is which), and you should be fine.
Someone has already created the page in question for you, by I do recommend that you try creating pages yourself in the future using the method I specified. If you still need some help doing so, let me know and I'll assist you wherever I can.
I believe the counter for the picture series of badges only updates when you add a picture to an article page. Simply uploading a picture doesn't count toward earning a badge. I'm not sure if the template adding an existing image counts either (the badges are pretty simple in their behaviour), although I believe it does count if a picture already exists and you create a page, with the template adding in the pic automatically.
Thats why i create a page and then i go back and i add a picture... strange, first 3 times went ok then stop... aaaaa i know what happen! last 3 pics i deleted the [[image: part before i add the picture and it didnt count them :/.
@Odelgard What you did isn't technically incorrect, but the method Malicent just detailed is the easier way. Feel free to create categories using either method, although I mostly use Malicent's method myself.
