Avatar missing when posts published to FB application using Simple Facebook Conn

I’m using version 0.21 of Simple Facebook Connect on a WP 2.9.2 multi-user blog.

I’ve made a FB application id=100189890029030 which I want to act as a news feed for the organisation.

Everything works fine except the default FB question mark displays to the left where the poster’s avatar should be.

FB does display the correct icon below each post next to: “xx minutes ago via…”

I have activated SFC – Login, connected my accounts, made sure I logged in using my FB credentials, and published a post which I am the author of.

I would be happy to replace the question mark with the organisation logo, but I cannot find where to upload this.

There is a FB page at Application Information – edit – Step 2:Picture, but this seems to be broken.

It will not upload a new 2.5KB logo, and the Thumnail Version cannot be altered. The Current Picture is the logo and looks fine, but Remove Picture does nothing.

Any hints about what I should look at next would be appreciated.
