[why is profile picture changing dimensions when zoomed?]

Hello,

I uploaded a 512x512 pic for my web profile avatar and when you click on zoom it resizes to something like 200x1000.  I looked around and this is true of every profile pic.  I know it's not my browser because I've heard others say the same thing...

[Ok, why hasn't my US$100 limit increased to US$300 on Day 8?]

I am new and have reached day 8 but am still being prevented from spending more than US$100 a month.  What gives???
