Thanks for your question.
If you navigate to the “Field-level substitution parameters/Field-level data sources” section of the Settings/Media library Assistant Documentation tab you will find many values you can add to your [mla_gallery] display. For your application, dimensions, height, width, pixels and orientation would be of interest.
Displaying the values can be done by adding them to the caption, e.g., adding mla_caption="{+dimensions+}" as a shortcode parameter or defining a custom markup template that includes them.
Sorting is a bit more involved, since the values are not available in the database when the query is done to select items for the gallery. You can define a Custom Field mapping rule and populate the field with the value(s) you want. Once that’s done you can query and/or sort your [mla_gallery] display on the custom field value. The “MLA Gallery Shortcode/Order, Orderby” section of the Documentation has more information.
I am on the road, so this is a quick answer. If you need more specific guidance regarding the above suggestions, post an update her and I will follow up when I return home. Thanks for your interest in the plugin.
