Add info to Lightbox2 plugin

Hello Omeka Community,

I have successfully added the Lightbox2 plugin:

What I’m trying to achieve is, when the image is open, in the bottom left corner, it mentions the sequence of image. I’d like to add the filename next to it, just without the file extension.

I tried different variations, but nothing worked. Does anyone know which file needs to be changed to make this happen?

Thank you!
