The Joomla! component Expose 4.6.3 has problems with FireFox 3.0.17
The hyperlinked images can’t be clicked on directly. You have to right click and then click on the link while the little window for Flash Settings is open.
Upgrading to the latest FireFox version should fix the issue. Version 3.6 is known to work with Expose 4.
or you can link directly to the project files
If your hosting account is on Go Daddy (or you verify that you have trouble uploading images using the frontend for Expose) then you will probably need to download Album Manager desktop application.
