Since release of Adobe Flash 10 Joomla flash uploader (for files and images) has stop working.
Since joomla ver. 1.5.8 it is possible (trough main configuration) to disable such flash uploader and the standard form is displayed.
Existing extension like JAM (Joomla Advanced Message) were based on joomla flash uploader and now is impossible to use it.
Where can I start from to make existing extensions working with standard upload form?
