Thanks for an interesting question. The current MLA production version does not have this ability but I was able to modify an existing option/format code to give you a possible solution.
I have uploaded a new MLA Development Version dated 20190302 that contains the new feature. You can find step-by-step instructions for using the Development Version in this earlier topic:
PHP Warning on media upload with Polylang
With the Development Version you can use the [mla_gallery] shortcode to display the “age” of an item. For example, you can code something like:
[mla_gallery post_parent=all posts_per_page=10 orderby="date" order="DESC" mla_caption="{+upload_date,date('%s',age)+} since this photo was uploaded"]
This will display the ten most recent items with an appropriate caption. The date('%s',age) option/format value converts the uploaded on date to a human readable age.
It would be great if you can install the Development Version and let me know if it works for you. I will leave this topic unresolved until I hear back from you. Thanks for inspiring this new MLA feature and for your interest in the plugin.
Just tested it and it works perfectly!
Thanks for this plugin and all your work to support and improve it. I really appreciate you adding this functionality and doing it so quickly.
I have released MLA version 2.79, which contains the new features for your application.
I am marking this topic resolved, but please update it if you have any trouble with the new version. Thanks again for your help with this MLA improvement.
