Add Overlay

Hi

I downloaded image overlay and installed it like described in the README.txt file. There I also followed the way of configuring it, but when I do open a node (containing a uploaded image) there is a the tab called overlay tools. When clicking there I just get the header of the node - nothing else underneath.

It the "readme" it says that there should be a tab "Add Overlay" which I do not see.

The temp file folder is under sites/all/default/files/temp and I uploaded also a sample symbol over the web interface... then I have read that there are problems with internet explorer, but it does not work for me in ff or chrome either. I also did setup the permissions for my user, although he is already admin.

Am I doing something basic wrong or is this a bug!

Please - I really would need to get this module to work - it would be extremely useful for me!

Many Thanks in advance!!!

Cheers
