How to output file (image) alt form Files in Shopify

Hello
Im looking for the possibility to output image_alt for the image uploaded into Files
I do have incremental loop to output custom images and everything works like a charm
I added text alt to the images in Files, but have to idea hot to display it as a text under the images
Images are there - please see come

{% for i in (1..51) %}
{% capture code_img %}{{ handle }}_{{ i }}.jpg{% endcapture %}
{% assign mod = forloop.index | modulo: 37 %}

{%- liquid
case mod
xxxxxx all my cases here within layout
endcase
%}

{{ code_img | file_url | img_tag }} ////////Thats where I need to output img_alt somehow as a variable something like {{ code_img.alt}}??? {% endfor %}

Start by reviewing the Liquid filters shown in the example, especially file_url and img_tag, and determine whether file metadata is available to the template. The issue does not name a source file or test, and it has no comments or linked pull request. Done would mean establishing whether alt text for Files can be accessed and documenting or implementing the supported behavior.
