I have been battling with this problem for almost 2 weeks now, all uploaded images only show as attachment with a number behind it. Urljet is my hosting site and I asked them to help me with this but unfortunately they cant resolve the problem either. I found a thread with the same problem on vb.com which was asked in August but never answered by the staff. I read through 5 pages of threads here and do not see a similar problem either. We disabled all mods and hooks, cleared cache, tried from several different computers with different browsers, upgraded to 4.2.1, rebuild attachments and still nothing works.
