Broken avatar

Hy!

I used this plugin on my page and it has a bug. I used the iFlyChat plugin for chatting, but when a user has the default BPCover Avatar, the avatar is broken on chat.

Can you see here:

Image nothing showed on this link(that used the chat):
http://i2.wp.com/hungarycs.hu/wp-content/plugins/bp-cover//images/default_user.jpg&s=50&r=G

It write: “We cannot complete this request, remote data was invalid”
Without “&s=50&r=G” this link is work good:
http://i2.wp.com/hungarycs.hu/wp-content/plugins/bp-cover//images/default_user.jpg

If I set an another avarat, it displayed good.
The problem is with the BPCover other with iFlyChat?

(I have so bad English. I learn it, but I have a lots of spelling mistakes, sorry. When you can’t understand me, please write a comment.)
