How to change the name of index.html file in lightbox plugin?

Q: Dear Support,

I would like to know, if it is possible to rename the index.html file, when I publish it to folder because I've already have index.html file and I don't want to have it overwritten by your index.html

A: Yes, it is possible to make it. When you chose the folder for publishing, there is an 'Index file name' area below where you can rename the index.html file.
