Help for 23

I'm having 23hq.com posting updates on my Facebook account using ping.fm. Unfortunately it attaches random images from other users, instead of my images - see this screencap (I haven't found a way to convert usernumbers to usernames, so I really can't see who is the source of these images, but the URL to the last image is http://www.23hq.com/5473645/5865278_85d5a9d316859ecf7a10586b1cd5e6f5_quad100.jpg).

I'm not really sure if this is a 23hq.com thing or a ping.fm thing :(

In kind regards,
Henrik
