Ask @dcthegamr ,he knows how to add the pictures directly onto your account.

(Note: It will require him accessing your account, so i'd suggest making a throwaway password for him to use, then once he's done, swapping back to your actual pass)

Adding your own profile photos used to be much easier, but the code used to do it broke so now you have to manually draw your own via the dsipaint art application. Hope this helps
