I guess I am getting ahead of myself to worry about this, but I just was reading about the development of Joomla 1.6.   

2. The legacy mode will be gone: All extensions must run Joomla 1.6 native. Some small changes to the code will be required to bring extensions in line with the new Access Control List features. You will not be able to run Joomla 1.0 components in legacy as you were in Joomla 1.5.

I sure hope you will keep developing the Ajax gallery so that when Joomla turns the next corner we can continue to benefit from your great component!

Good!  I like knowing your gallery is available - it is my "go to" component when a client wants a photo gallery.
