Just keep posting pictures (nice carbs, by the way!) , - at some point I will find the bug in the forum extension - the pictures *are* there, and as Anders experienced, they turn up when you change into normal forum-board view. (which you do when replying etc)
The blogging extension is very minimalistic, and the blogs are really implemented as standard forum posts, - in hidden foldes in the "General Matra Related" section.
This is a direct link to Razorback's carb Blog as a forum thread: http://www.matrasport.dk/forum/index.php/board,29.0.html
I will keep searching for the error - I have already found some interesting blog-related errors in the forum log that I will track.
