Something weird is going on with photo's uploaded as attachments. When I create a new message and want to add photo's to it, I click "manage attachments". Upload the photo's and click the insert-button. When I than submit the image, the system won't insert the actual photo. Instead, it just inserts a hyperlink to the image (which doesn't seem to work either).
However. When I then edit the mail post and re-insert the same photo, the photo is recognized as such and shown correctly.
This doesn't happen all the time though...
