Maximum file size is only 2mb so can't upload here unfortunately.
Here's the thread http://www.the-sps.org/threads/problem-displaying-attachments.23123
Edit: initially I thought the problem was the file name but this apparently isn't the cause. I allow pictures up to 10mb so strange. The server logs show 2 errors today that would appear to be linked to this but it says in those user account unknown..
