Link from the gallery image

Thanks for your question and for including the full text of your shortcode; very helpful.

You can use two of the [mla_gallery] parameters to add these attributes to the links around each thumbnail. Here is a shortcode that is working well on my system:

[mla_gallery size=icon post_mime_type=application/pdf post_parent=all link=file size=medium]
mla_target="_blank"
mla_link_attributes='rel="noreferrer noopener"'
mla_caption='<a href="{+file_url+}" target="_blank" rel="noreferrer noopener">{+title+}</a>'
[/mla_gallery]

Note the use of single quotes around the mla_link_attributes value, so the attribute can be surrounded by double quotes.

I hope that gives you what you need for your application. I am marking this topic resolved, but please update it if you have problems or further questions regarding the above solution. Thanks for your interest in the plugin.
