default gallery image name

[Inlens]

I need to change default gallery image name (now it takes from file's name) to ***

Simple, just all names of uploading images should be ***

You can type *** into first image name, and then click on "Apply All."

Or do you want same name applied to all images, regardless of who uploaded?

Users do not have to do anything)

Only if they want they can set the title of image
