will Lightbox Gallery 1.1 work with zen cart v1.3.9d?

I'm guessing it will. However, when i upload the plugin files from the folder 'cart' as the instructions say, i have to overwrite a few files already in the zencart directory (on my ftp)

is this ok? or should i keep the existing files from v1.3.9d? or use the ones from lightbox gallery 1.1?

thanks

I also read that version 1.5 is available? On the zen cart page it only shows a link for version 1.1

nevermind.. this may be too much trouble than it's worth.

Gallery2 looks much more promising.. http://codex.gallery2.org/Gallery2:Modules:zencart
