on a previous forum post i tried to upload a .png screenshot but i kept getting "The file could not be uploaded." - tried two different browsers - i then tried HTML tags as it clearly says are supported but as you can see these do not work
<img src="http://www.juce.com/sites/default/files/images/template/JUCE-logo-002.png" alt="anImg" />
<a href="http://www.juce.com/">aLink</a>
the only way i could put an image in a post in the default "Filtered HTML" mode was by using the toolbar button - i later found that these tags work only if you switch to "BBCode" mode
