How to display filename?

[pbt39ppc]

It would be useful, but i cant find how

1. display filename in the gallery under the image (using yaml is a nightmare with 1000 + images)
2. display filename on the ug-textpanel (also, without using yaml for each file)

This is describe what i need , but text on the textpanel is something like {{ image.filename|rtrim('.jpg') }}

without unitegallery plugin i'm using something like

<div class="someoverlay">
 {{ image.filename|rtrim('.jpg') }}
 {{ image.meta.alt_text }}
</div>

this will display filename (all my images is jpg)
and if there is a file image-filename.jpg.meta.yaml with alt_text: text here it will display "text here" as another line.
i think it would be useful to add code for that in template/script
